EN 10088-3:2014 (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 document 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 19 and 25 (see also Annex A). 6.3 Chemical composition 6.3.1 The chemical composition requirements given in Tables 2 to 5 apply in respect of the chemical composition according to the cast analysis. 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 austenitic, austenitic-ferritic and ferritic stainless steels the specifications in Tables 8, 9 and 10 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 apply for hot worked products of every condition, condition 1U and semi-finished products 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 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 Tables 18 and 19 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 25 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 Tables 20 to 24 apply for the 0,2 %- and 1 %- proof strength at elevated temperatures.

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 usual 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 the tensile test. 6.9 Dimensions and tolerances on dimensions and shape The dimensions and the tolerances on dimensions are to be agreed at the time of enquiry and order, as far as possible with reference to the dimensional standards listed in Table 7 and in Annex C. 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 in Annex C, they may be agreed at the time of enquiry and order.

EN 10088-3:2014 (E) 10 7 Inspection and testing 7.1 General The appropriate process control, inspection and testing shall be carried out to ensure that the product complies with the requirements of the order. This includes the following: — suitable frequency of verification of the dimensions of the products; — adequate intensity of visual examination of the surface quality of the products; — 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 is determined in the light of the degree of consistency that has been determined by the evidence of the quality system. In view of this, verifications by specific tests for these requirements are not necessary unless otherwise agreed. 7.2 Agreement on tests and inspection documents 7.2.1 Products complying with this European Standard shall be ordered and delivered with one of the inspection documents as specified in EN 10204. The type of document shall be agreed upon at the time of enquiry and order. If the order does not contain any specification of this type, a test report 2.2 shall be issued. 7.2.2 If it is agreed to issue a test report 2.2 in accordance with EN 10204 it shall indicate the following information: a) information groups A, B and Z of EN 10168; b) results of the cast analysis in accordance with the code numbers C71 to C92 in EN 10168. 7.2.3 If the issuing of an inspection certificate 3.1 or 3.2 according to EN 10204 has been agreed, specific inspections according to 7.3 are to be carried out and the following information shall be given in the inspection document with the code numbers and details required by EN 10168: a) under 7.2.2 a); b) under 7.2.2 b); c) results of the mandatory tests marked in Table 26, second column, by 'm'; d) results of any optional tests or inspections agreed at the time of enquiry and order. 7.3 Specific inspection and testing 7.3.1 Extent of testing The tests to be carried out, either mandatorily (m) or by agreement (o) and the composition and size of the test units, and the number of sample products, samples and test pieces to be taken are given in Table 26. 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. SIST EN 10088-3:2015

EN 10088-3:2014 (E) 11 7.3.2.2 The 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 appropriate European Standards. 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 CEN/TR 10261. 7.4.2 The tensile test at room temperature shall be carried out in accordance with EN ISO 6892-1, 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.
