See also Annex B to EN 10088-1:2005. SIST EN 10088-4:2009
EN 10088-4:2009 (E) 8 6 Requirements 6.1 Steelmaking process Unless a special steelmaking process is agreed at the time of enquiry and order, the steelmaking 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 6 and, where different alternatives exist, to the treatment conditions given in Tables 7 to 11, 13 and 14 (see also Annex A). 6.3 Chemical composition 6.3.1 The requirements given in Tables 1 to 4 shall apply with respect to 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 10088-2 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 1 to 4 by the values listed in Table 5. 6.4 Chemical corrosion properties
Referring to resistance to intergranular corrosion as defined in EN ISO 3651-2, for ferritic, austenitic and austenitic-ferritic steels the specification in Tables 7, 10 and 11 shall apply. EN ISO 3651-2 shall not be applicable for testing martensitic and precipitation hardening steels. NOTE The corrosion resistance of stainless steels is very dependant 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 7 to 11 shall apply for the relevant specified heat treatment condition. This does not apply to the process route 1U (hot rolled, not heat treated, not descaled). If the products are to be supplied in a non-heat-treated condition, the mechanical properties specified in 7 to 11 shall be obtained from reference test pieces which have received the appropriate heat treatment (simulated heat treatment). For cold worked products, the tensile strength levels at ambient temperature as specified in Table 13 shall apply. The available tensile strength levels in the cold worked condition are indicated in Table 15. Alternatively, cold worked products can be ordered according to their 0,2%-proof strength as given in Tables 14 and 16. 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 12 shall apply for the 0,2 %- and 1 %-proof strength of austenitic steels at elevated temperatures. SIST EN 10088-4:2009
EN 10088-4:2009 (E) 9 6.6 Surface quality Slight surface imperfections, inherent in the rolling process, shall be permitted. When products are delivered in coil form, the degree and extent of such imperfections can to be greater, due to the impractibility of removing short lengths of coil. For hot-rolled quarto-plates (symbol P in Tables 7 to 11), the requirements in EN 10163-2, class A2, shall apply unless otherwise agreed. For other products, where necessary, more precise requirements on surface quality can be agreed at the time of enquiry and order. 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 austenitic and austenitic-ferritic stainless steel flat products ≥ 6 mm shall be in accordance with EN 10307. 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). EN 10029 shall normally only be applied for product form P (individually rolled plates, "quarto plates") and not for product form H (continuously rolled strip and plate), for which EN 10051 shall be applied. When applying EN 10029, thickness tolerance class B shall apply unless specifically agreed otherwise. 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 Annex B, 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. SIST EN 10088-4:2009
EN 10088-4:2009 (E) 10 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 17, second column, by "m"; d) the result 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 17. 7.3.2 Selection and preparation of samples and test pieces 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 samples for the tensile test shall be taken in accordance with Figure 1 in such a way that they are located halfway between the centre and a longitudinal edge. Impact test samples shall be taken from the same location. The samples shall be taken from products in the delivery condition. If agreed, the samples may be taken before flattening. 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. For direction of bending the test piece in the resistance to intergranular corrosion test, see Figure 2. 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 taking into account the additional or deviating conditions specified in Figure 1, footnote a. 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. SIST EN 10088-4:2009
EN 10088-4:2009 (E) 11 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, the Rockwell hardness test in accordance with EN ISO 6508-1, and the Vickers hardness test in accordance with EN ISO 6507-1. 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. 7.5 Retests Shall be according to EN 10021. 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 European 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. 8.2.1.1 Initial type testing Initial type testing (see Table ZA.3) shall be performed to show conformity with this European Standard for a steel product being put onto the market and: a) at the beginning of the production of a new or modified steel product design; SIST EN 10088-4:2009
EN 10088-4:2009 (E) 12 b) at the beginning of a new or modified method of production. 8.2.1.2 Type testing of a steel product 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: a) if it has been established that the performance characteristics compared with the already tested steel products have not been affected or

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 a special steelmaking process is agreed at the time of enquiry and order, the steelmaking 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 process route given in Table 6 and, where different alternatives exist, to the treatment conditions given
in Tables 7 to 11, 13 and 14 (see also Annex A).
6.3 Chemical composition
6.3.1 The chemical composition requirements given in Tables 1 to 4 shall apply with respect to 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 2 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 1 to 4
by the values listed in Table 5.
6.4 Chemical corrosion properties
Referring to resistance to intergranular corrosion as defined in EN ISO 3651-2, for ferritic, austenitic and
austenitic-ferritic steels the specification in Tables 7, 10 and 11 shall 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 dependant 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.

prEN 10088-4:2005 (E)
6.5 Mechanical properties
6.5.1 The mechanical properties at room temperature as specified in Tables 7 to 11 shall apply for the
relevant specified heat treatment condition. This does not apply to the process route 1U (hot rolled, not heat
treated, not descaled).
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 7 to 11 shall be obtained from reference test pieces which have received
the appropriate heat treatment (simulated heat treatment).
For cold worked products, the tensile strength levels at ambient temperature as specified in Table 13 shall
apply. The available tensile strength levels in the cold worked condition are indicated in Table 15.
Alternatively, cold worked products can be ordered according to their 0,2%-proof strength as given in Tables
14 and 16.
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 12 shall apply for the 0,2 %- and 1 %-proof strength of austenitic steels at
elevated temperatures.
6.6 Surface quality
Slight surface imperfections, inherent in the rolling process, are permitted.
When products are delivered in coil form, the degree and extent of such imperfections may be expected to be
greater, due to the impractibility of removing short lengths of coil. For hot-rolled quarto-plates (symbol P in
Tables 7 to 11), the requirements in EN 10163-2, class A2, apply unless otherwise agreed. For other products,
where necessary, more precise requirements on surface quality may be agreed at the time of enquiry and
order.
6.7 Internal soundness
The products shall be free of internal defects which would exclude them from being used for their intended
purpose. Ultrasonic testing of austenitic and austenitic-ferritic stainless steel flat products ≥ 6 mm may be
agreed at the time of enquiry and order in accordance with EN 10307.
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
The dimensions and the tolerances on dimensions and shape shall be agreed at the time of enquiry and order,
as far as possible and in so far they do not conflict with regulatory requirements with reference to the
dimensional standards listed in the normative references. EN 10029 shall normally only be applied for product
form P (individually rolled plates, "quarto plates") and not for product form H (continuously rolled strip and
plate), for which EN 10051 shall be applied. When applying EN 10029, thickness tolerance class B shall apply,
unless specifically agreed otherwise 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.

---------------------- Page: 9 ----------------------
prEN 10088-4:2005 (E)
6.10.2 If the tolerances on mass are not specified in the dimensional standard listed in the normative
references, they may be agreed at the time of enquiry and order.
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 17, second column, by "m";

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.
