EN 10088-5:2009 (E) 7 b) the product form (e. g. round bars, square bars or rod); c) the nominal dimensions and, where an appropriate dimensional standard is available, (see Table 7 and Annex B) the number of the standard plus any choice of requirements; d) if there is no dimensional standard, the nominal dimensions and tolerances required; e) the type of material (steel); f) the number of this European Standard; g) the steel name or steel number; h) the symbol for the desired heat treatment or cold worked condition, if for the relevant steel in the tables for the mechanical properties more than one treatment condition is covered; i) the desired condition (see symbols in Table 7); j) verification of internal soundness, if required; k) the type of inspection certificate (3.1 or 3.2) according to EN 10204; l) regulatory marking requirements (see Annex ZA). EXAMPLE 10 t round bars of a steel grade with the name X5CrNi18-10 and the number 1.4301 as specified in EN 10088-5 of 50 mm diameter, dimensional tolerances as specified in EN 10060, in condition 1D (see Table 7), inspection certificate 3.1 as specified in EN 10204 and declaration of conformity: 10 t round bars EN 10060-50 Steel EN 10088-5-X5CrNi18-10+1D Inspection certificate 3.1, CE or 10 t round bars EN 10060-50 Steel EN 10088-5-1.4301+1D Inspection certificate 3.1, CE 5 Classification of grades Steels covered in this European Standard are classified according to their structure into a) ferritic steels; b) martensitic steels; c) precipitation hardening steels; d) austenitic steels; e) austenitic-ferritic steels. See also Annex B to EN 10088-1:2005. SIST EN 10088-5:2009

EN 10088-5:2009 (E) 8 6 Requirements 6.1 Steelmaking process Unless otherwise agreed at the time of enquiry and order, the steelmaking and manufacturing process for steels conforming to this European Standard shall be at the discretion of the manufacturer. 6.2 Delivery condition The products shall be supplied by reference to the process route given in Table 7 and, where different alternatives exist, to the treatment conditions given in Tables 8 to 18 and 20 (see also Annex A). 6.3 Chemical composition 6.3.1 The requirements given in Tables 2 to 5 shall apply in respect of the chemical composition according to the cast analysis. If grades other than those included in this European Standard are required for construction purposes, they shall comply with EN 10088-3 and be in conjunction with the requirements of this European Standard. 6.3.2 The product analysis may deviate from the limiting values for the cast analysis given in Tables 2 to 5 by the values listed in Table 6. 6.4 Chemical corrosion properties Referring to resistance to intergranular corrosion as defined in EN ISO 3651-2, for ferritic, austenitic and austenitic-ferritic stainless steels the specifications in Tables 8, 11 and 12 apply.

EN ISO 3651-2 shall not be not applicable for testing martensitic and precipitation hardening steels. NOTE The corrosion resistance of stainless steels is very dependent on the type of environment and can therefore not always be clearly ascertained through laboratory tests. It is therefore advisable to draw on the available experience of the use of the steels. 6.5 Mechanical properties 6.5.1 The mechanical properties at room temperature as specified in Tables 8 to 12 shall apply for hot worked products of every condition, condition 1U excluded, for cold processed products in condition 2D (excluding wire), and for each specified heat treatment condition. For cold processed products of every specified condition, condition 2D and wire excluded, and each specified heat treatment condition, the mechanical properties at room temperature as specified in Tables 13 to 17 shall apply. For these products, the condition is the prime property with the mechanical properties secondary. If the products are to be supplied in a non-heat-treated condition, the mechanical properties specified in Tables 8 to 17 shall be obtained from reference test pieces which have received the appropriate heat treatment (simulated heat treatment). For wire, the properties as specified in Table 18 shall apply. For bars which are intentionally cold work hardened in order to increase their tensile strength to a specified level, the mechanical properties at room temperature as specified in Table 20 shall apply. For these products, the mechanical properties are prime, with the condition a secondary property. SIST EN 10088-5:2009

EN 10088-5:2009 (E) 9 NOTE Austenitic steels are insensitive to brittle fracture in the solution annealed condition. Because they do not have a pronounced transition temperature, which is characteristic of other steels, they are also useful for application at cryogenic temperatures. 6.5.2 The values in Table 19 shall apply for the 0,2%- and 1%- proof strength of austenitic steels at elevated temperatures. 6.6 Surface quality The available surface finishes are given in Table 7. Slight surface imperfections, inherent to the rolling process, shall be permitted. Exact requirements concerning maximum acceptable depth of discontinuities for bars, rods and sections in the relevant conditions are given in Table 1. Table 1 — Maximum acceptable depth of discontinuities for bars, rods and sections Conditions Product forms Permissible depth of discontinuities a Max. % of delivered weight in excess of permissible depth of discontinuities 1U, 1C, 1E, 1D Sections See EN 10163-3. 1U, 1C, 1E, 1D Rounds and rod See EN 10221. 1Xb, 2Hb, 2Db Rounds - max. 0,2 mm for d ≤ 20 mm - max. 0,01 d for 20 < d ≤ 75 mm - max. 0,75 mm for d > 75 mm 1 % Hexagons - max. 0,3 mm for d ≤ 15 mm - max. 0,02 d for 15 < d ≤ 63 mm 2 % Other bars - max. 0,3 mm for d ≤ 15 mm - max. 0,02 d for 15 < d ≤ 63 mm 4 % 1G, 2B, 2G, 2P Rounds Technically defect free by manufacture. 0,2 % a The depth of discontinuities shall be the distance, measured normally to the surface, between the bottom of the discontinuities and

that surface. b The order can require that the product shall be delivered with a surface being technically defect free by manufacture. In this case,

also the maximum % of delivered weight in excess of permissible depth of discontinuities shall be agreed.

For further information, e.g. roughness in conditions 2G and 2P, see Table 7. 6.7 Internal soundness

The products shall be free of internal defects which would exclude them from being used for their intended purpose. If verification of internal soundness is required, ultrasonic testing of H-beams with parallel flanges and IPE-beams shall be in accordance with EN 10306 and ultrasonic testing of steel bars shall be in accordance with EN 10308. 6.8 Formability at room temperature

Cold formability may be verified by elongation in the tensile test. 6.9 Dimensions and tolerances on dimensions and shape Dimensions and tolerances on dimensions and shape shall be declared by reference to the appropriate European Standard (see Annex B). Dimensions and tolerances on dimensions and shape not covered by European SIST EN 10088-5:2009

EN 10088-5:2009 (E) 10 Standards shall be in accordance with a national standard valid in the intended place of use of the product or as agreed at the time of enquiry and order. 6.10 Calculation of mass and tolerances on mass 6.10.1

When calculating the nominal mass from the nominal dimensions the values given in

EN 10088-1 shall be used as a basis for the density of the steel concerned. 6.10.2

If the tolerances on mass are not specified in the dimensional standard listed in Table 7 or the normative references, they may be agreed at the time of enquiry and order. 7 Inspection and testing 7.1 General The process control, inspection and testing shall be carried out according to 8.3 to ensure that the product complies with the requirements of both this European Standard and the order.

This includes the following: a) A suitable frequency of verification of the dimensions of the products; b) An adequate intensity of visual examination of the surface quality of the products; c) An appropriate frequency and type of test to ensure that the correct grade of steel is used. The nature and frequency of these verifications, examinations and tests shall be in accordance with the manufacturer's written procedures in compliance with 8.3. 7.2 Agreement on tests and inspection documents Products declaring compliance with this European Standard shall be delivered with an inspection certificate 3.1 or 3.2 as specified in EN 10204. The type of certificate shall be agreed upon at the time of enquiry and order. If the order does not contain any specification of this type, inspection certificate 3.1 shall be issued.

The specific inspection described in 7.3 shall be carried out and confirmed together with the following information in the inspection certificate with the code numbers and details required by EN 10168:2004. a) the information groups A, B and Z of EN 10168:2004; b) the results of the cast analysis in accordance with the code numbers C71 to C92 in EN 10168:2004; c) the results of the tests marked in Table 21, second column, by 'm'; d) the results of any optional test or inspections agreed at the time of enquiry and order; e) the regulatory information (see Annex ZA).

In addition, the stipulations in 7.3.2.2 apply for the mechanical tests. 7.3.2.2 The samples for the tensile test shall be taken in accordance with Figures 1 to 3. Impact samples shall be taken from the same location. The samples shall be taken from products in the delivery condition. If agreed, samples from bars may be taken before straightening. For samples to be given a simulated heat treatment the conditions for annealing, hardening and tempering shall be agreed. 7.3.2.3 Samples for the hardness test and for the resistance to intergranular corrosion test, shall be taken from the same locations as those for the mechanical tests. 7.4 Test methods 7.4.1 The chemical analysis shall be carried out using the appropriate European Standard for the element being analysed. In the absence of an appropriate European Standard, the choice of a suitable physical or chemical analytical method for the analysis shall be at the discretion of the manufacturer. The manufacturer shall declare the test method used, if required. The list of available European Standards on chemical analysis is given in CEN/TR 10261. 7.4.2 The tensile test at room temperature shall be carried out in accordance with EN 10002-1, this generally being with proportional test pieces having a gauge length L0 = 5,65 √S0. (S0 = cross-section of the parallel length). In cases of doubt and in referee testing these test pieces shall be used. For wire of nominal diameter < 4 mm, the tensile test shall be made directly on the product using a gauge length of 100 mm. The tensile strength, elongation after fracture and the 0,2 %-proof strength shall be determined. In addition, for austenitic steels only, the 1%- proof strength shall be determined. 7.4.3 The tensile test for austenitic steels at elevated temperature shall be carried out in accordance with EN 10002-5. If the proof strength is to be verified for austenitic steels the 0,2%- and the 1%- proof strength shall be determined. 7.4.4 The impact test shall be carried out in accordance with EN 10045-1 on test pieces with a V-notch. The average obtained from three test pieces shall be considered to be the test result (see also EN 10021). 7.4.5 The Brinell hardness test shall be carried out in accordance with EN ISO 6506-1. 7.4.6 The resistance to intergranular corrosion shall be tested in accordance with EN ISO 3651-2 for ferritic, austenitic and austenitic-ferritic steels. 7.4.7 Dimensions and dimensional tolerances of the products shall be tested in accordance with the requirements of the dimensional standard relevant to the product form.

prEN 10088-5:2005 (E) 7 EXAMPLE 10 t round bars of a steel grade with the name X5CrNi18-10 and the number 1.4301 as specified in EN 10088-5 of 50 mm diameter, dimensional tolerances as specified in EN 10060, in condition 1D (see Table 7), inspection certificate 3.1 as specified in EN 10204 and declaration of conformity: 10 t round bars EN 10060-50 Steel EN 10088-5-X5CrNi18-10+1D Inspection certificate 3.1, CE or 10 t round bars EN 10060-50 Steel EN 10088-5-1.4301+1D Inspection certificate 3.1, CE 5 Classification of grades Steels covered in this European Standard are classified according to their structure into  ferritic steels,  martensitic steels,  precipitation hardening steels,  austenitic steels,  austenitic-ferritic steels. See also Annex B to EN 10088-1. 6 Requirements 6.1 Steelmaking process Unless otherwise agreed at the time of enquiry and order, the steelmaking and manufacturing process for steels conforming to this European Standard shall be at the discretion of the manufacturer. 6.2 Delivery condition The products shall be supplied in the delivery condition agreed at the time of enquiry and order by reference to the conditions given in Table 7 and, where different alternatives exist, to the treatment conditions given in Tables 8 to 18 and 20 (see also Annex A). 6.3 Chemical composition 6.3.1 The chemical composition requirements given in Tables 2 to 5 shall apply in respect of the chemical composition according to the cast analysis. If grades other than those included in this European standard are required for construction purposes, they shall comply with part 3 and be in conjunction with the requirements of this European standard. 6.3.2 The product analysis may deviate from the limiting values for the cast analysis given in Tables 2 to 5 by the values listed in Table 6.

prEN 10088-5:2005 (E) 8 6.4 Chemical corrosion properties Referring to resistance to intergranular corrosion as defined in EN ISO 3651-2, for ferritic, austenitic and austenitic-ferritic stainless steels the specifications in Tables 8, 11 and 12 apply.

NOTE 1 EN ISO 3651-2 is not applicable for testing martensitic and precipitation hardening steels. NOTE 2 The corrosion resistance of stainless steels is very dependent on the type of environment and can therefore not always be clearly ascertained through laboratory tests. It is therefore advisable to draw on the available experience of the use of the steels. 6.5 Mechanical properties 6.5.1 The mechanical properties at room temperature as specified in Tables 8 to 12 shall apply for hot worked products of every condition, condition 1U excluded, for cold processed products in condition 2D (excluding wire), and for each specified heat treatment condition. For cold processed products of every specified condition, condition 2D and wire excluded, and each specified heat treatment condition, the mechanical properties at room temperature as specified in Tables 13 to 17 shall apply. For these products, the condition is the prime property with the mechanical properties secondary. If by agreement at the time of ordering the products are to be supplied in a non-heat-treated condition, the mechanical properties specified in Tables 8 to 17 shall be obtained from reference test pieces which have received the appropriate heat treatment (simulated heat treatment). For wire, the properties as specified in Table 18 shall apply. For bars which are intentionally cold work hardened in order to increase their tensile strength to a specified level, the mechanical properties at room temperature as specified in Table 20 shall apply. For these products, the mechanical properties are prime, with the condition a secondary property. NOTE Austenitic steels are insensitive to brittle fracture in the solution annealed condition. Because they do not have a pronounced transition temperature, which is characteristic of other steels, they are also useful for application at cryogenic temperatures. 6.5.2 The values in Table 19 shall apply for the 0,2%- and 1%- proof strength of austenitic steels at elevated temperatures. 6.6 Surface quality The available surface finishes are given in Table 7. Slight surface imperfections, inherent to the rolling process, are permitted. Exact requirements concerning maximum depth of acceptable defects for bars, rods and sections in the relevant conditions are given in Table 1.

surface. b At the time of enquiry and order it may be agreed that the product shall be delivered with a surface being technically defect free by

manufacture. In this case, also the maximum % of delivered weight in excess of permissible defect depth shall be agreed.

For further information, e.g. roughness in conditions 2G and 2P, see Table 7. 6.7 Internal soundness

The products shall be free of internal defects which would exclude them from being used for their intended purpose. At the time of enquiry and order ultrasonic testing of H-beams with parallel flanges and IPE-beams may be agreed in accordance with EN 10306 and ultrasonic testing of steel bars may be agreed in accordance with EN 10308. 6.8 Formability at room temperature

Cold formability may be verified by elongation in tensile test. 6.9 Dimensions and tolerances on dimensions and shape Dimensions, tolerances on dimensions and shape of profiles not covered by European Standards shall be in accordance with a national standard valid in the intended place of use of the product or as agreed at the time of enquiry and order. 6.10 Calculation of mass and tolerances on mass 6.10.1

When calculating the nominal mass from the nominal dimensions the values given in

EN 10088-1 shall be used as a basis for the density of the steel concerned. 6.10.2

If the tolerances on mass are not specified in the dimensional standard listed in Table 7 or the normative references, they may be agreed at the time of enquiry and order.

prEN 10088-5:2005 (E) 10 7 Inspection and testing 7.1 General The appropriate process control, inspection and testing shall be carried out according to 8.3 to ensure that the product complies with the requirements of both this European standard and the order.

This includes the following:  A suitable frequency of verification of the dimensions of the products.  An adequate intensity of visual examination of the surface quality of the products.  An appropriate frequency and type of test to ensure that the correct grade of steel is used. The nature and frequency of these verifications, examinations and tests shall be determined in the light of the degree of conformity that has been determined by the evidence of the factory production control system. In view of this, verifications by additional specific tests for these requirements are not a requirement of this document. 7.2 Agreement on tests and inspection documents 7.2.1 At the time of ordering the type of inspection document in accordance with EN 10204 may be agreed for each delivery. 7.2.2 If it is agreed to issue a test report in accordance with EN 10204:2004, 2.2, it shall indicate the following information: a) the information groups A, B and Z of EN 10168:2004; b) the results of the cast analysis in accordance with the code numbers C71 to C92 in EN 10168:2004; c) the regulatory information (see Annex ZA). 7.2.3 If the issuing of an inspection certificate according to EN 10204:2004, 3.1 or 3.2, has been agreed, specific inspections according to 7.3 shall be carried out and the following information shall be given in the inspection document with the code numbers and details required by EN 10168:2004: a) as under 7.2.2 a); b) as under 7.2.2 b); c) the results of the tests marked in Table 21, second column, by 'm'; d) the results of any optional test or inspections agreed at the time of enquiry and order; e) the regulatory information (see Annex ZA). 7.3 Specific inspection and testing 7.3.1 Extent of testing The tests to be carried out and the composition and size of the test units and the number of sample products, samples and test pieces to be taken shall be as in Table 21.

prEN 10088-5:2005 (E) 11 7.3.2 Selection and preparation of samples 7.3.2.1 Sampling and sample preparation shall be in accordance with the requirements of EN ISO 14284 and EN ISO 377. In addition, the stipulations in 7.3.2.2 apply for the mechanical tests. 7.3.2.2 The test samples for the tensile test shall be taken in accordance with Figures 1 to 3. If it has been agreed that impact tests shall be carried out, the samples shall be taken from the same location. The samples shall be taken from products in the delivery condition. If agreed, samples from bars may be taken before straightening. For samples to be given a simulated heat treatment the conditions for annealing, hardening and tempering shall be agreed. 7.3.2.3 Samples for the hardness test and for the resistance to intergranular corrosion test, where requested, shall be taken from the same locations as those for the mechanical tests. 7.4 Test methods 7.4.1 The chemical analysis shall be carried out using the appropriate European Standard for the element being analysed. In the absence of an appropriate European Standard, the choice of a suitable physical or chemical analytical method for the analysis shall be at the discretion of the manufacturer. The manufacturer shall declare the test method used, if required. NOTE The list of available European Standards on chemical analysis is given in CR 10261. 7.4.2 The tensile test at room temperature shall be carried out in accordance with EN 10002-1, this generally being with proportional test pieces having a gauge length L0 = 5,65 √S0. (S0 = cross-section of the parallel length). In cases of doubt and in referee testing these test pieces shall be used. For wire of nominal diameter < 4 mm, the tensile test is made directly on the product using a gauge length of 100 mm. The tensile strength, elongation after fracture and the 0,2 %-proof strength shall be determined. In addition, for austenitic steels only, the 1%- proof strength shall be determined. 7.4.3 If the manufacturer wishes to claim a tensile test for austenitic steels at elevated temperature has been carried out, this shall be carried out in accordance with EN 10002-5. If the proof strength is to be verified for austenitic steels the 0,2%- and the 1%- proof strength shall be determined. 7.4.4 If the manufacturer wishes to claim an impact test has been carried out, it shall be carried out in accordance with EN 10045-1 on test pieces with a V-notch. The average obtained from three test pieces shall be considered to be the test result (see also EN 10021). 7.4.5 The Brinell hardness test shall be carried out in accordance with EN ISO 6506-1. 7.4.6 The resistance to intergranular corrosion shall be tested in accordance with EN ISO 3651-2. 7.4.7 Dimensions and dimensional tolerances of the products shall be tested in accordance with the requirements of the dimensional standard relevant to the product form. 7.5 Retests Shall be according to EN 10021.

prEN 10088-5:2005 (E) 12 8 Evaluation of conformity 8.1 General The conformity of a steel product to the requirements of this standard and with the stated values (including classes) shall be demonstrated by:  initial type testing,  factory production control by the manufacturer, including product assessment. For the purposes of testing, steel products may be grouped into families, where it is considered that the results for one or more characteristics from any one product within the family are representative for all steel products within that same family (a product may be in different families for different characteristics). The testing of samples taken at the works in accordance with the manufacturer's prescribed plan shall be the means of evaluation of conformity of the steel product delivered in accordance with this standard (see Table ZA.3). The report of such testing shall be in an inspection document in accordance with EN 10204. NOTE The assignment of tasks is given in Table ZA.3. 8.2 Initial type testing 8.2.1 General An initial type test is the complete set of tests or other procedures, in respect of the characteristics to be assessed, determining the performance of samples of products representative of the product type. Initial type testing (see Table ZA.3) shall be performed to show conformity with this standard for a steel product being put onto the market and:  at the beginning of the production of a new or modified steel product design,  at the beginning of a new or modified method of production. In case of type testing of a steel product for which initial type testing in accordance with this standard was already performed, type testing may be reduced:  if it has been established that the performance characteristics compared with the already tested steel products have not been affected or

 in accordance with the rules for families and/or direct or extended application of test results. 8.2.2 Characteristics The assessment of the following characteristics is required:  Tolerances on dimension and shape;  Elongation;  Tens
