Steels and nickel alloys for fasteners with specified elevated and/or low temperature properties
This European Standard specifies requirements for semi-finished products, bars and rods for fasteners with properties specified at elevated and/or low temperatures made of non-alloy and alloy (including stainless) steels and nickel alloys as given in Table 1.
The requirements of this standard may be applied also to the finished fasteners.
The general technical delivery conditions in EN 10021 also apply to products supplied in accordance with this European Standard.
NOTE Once this European Standard is published in the EU Official Journal (OJEU) under Directive 97/23/EC, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 97/23/EC is limited to technical data of materials in this European Standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 97/23/EC are satisfied, needs to be done.

7,89 kg/dm3; for austenitic CrNiMo steels: 8,00 kg/dm3. For all other steels a density of 7,85 kg/dm3 applies. 6 Classification and designation 6.1 Classification In accordance with EN 10020 the steel grades C35E, C45E and 20Mn5 are non-alloy special steels. All other steel grades are alloy special including austenitic steels. Additionally, austenitic nickel alloys are specified. 6.2 Designation The steel grades specified in this European Standard are designated with steel names and steel numbers. The steel names have been allocated in accordance with EN 10027-1.The corresponding steel numbers have been allocated in accordance with EN 10027-2. NOTE Explanation on the designation of nickel alloys: − name: the preceding chemical symbols indicate the main alloy elements and the figure immediately following indicates the average content of these alloys subsequently followed by the symbol for the other added important alloy elements; − material number: the structure is set out according to EN 10027-2 with the number 2 for the material group number; this material group comprises chemically resisting and heat resisting or creep resisting nickel and cobalt alloys. 7 Information to be supplied by the purchaser 7.1 Mandatory information The following information shall be supplied by the purchaser at the time of enquiry and order: a) the quantity required (mass or number of pieces); b) the type of product; c) the European Standard specifying the tolerances on dimensions and shape (see Clause 4) and the tolerance of mass and, if the relevant European Standard permits the purchaser certain options, e.g. regarding edge finishes or tolerance classes, specific information on these aspects; d) the nominal dimensions of the product; e) the number of this European Standard; f) the material name or number; SIST EN 10269:2014

Depending on the type (e.g. billet) and the dimensions of the product and the intended type of further processing the material, in special cases the delivery in the untreated condition may be agreed. 8.2.3 •• When delivery in a condition not covered in Table 4 or Table 5 is agreed, for the verification of compliance with the requirements of this European Standard tests on simulated treated samples may be agreed at the time of enquiry and order. In the case of billets, this simulated treatment may also include a hot forming operation. 8.2.4 •• By agreement at the time of enquiry and order, for the steels for quenching and tempering a stress relieving treatment after straightening may be specified. See footnote c) in Table B.1. 8.3 Chemical composition 8.3.1 The information in Table 1 applies for the chemical composition according to the cast analysis. 8.3.2 The product analysis shall not deviate from the specified values of the cast analysis as specified in Table 1 by more than the values given in Table 2. 8.3.3 For austenitic steels intergranular corrosion may occur.
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. 8.4 Mechanical properties 8.4.1 General The hardness and mechanical properties specified in this European Standard apply when billets, bars and rods are delivered in a condition given in Table 3, 4 or 5 and where the relevant tests are carried out in accordance with the sampling and testing conditions given in 10.2 and Clause 11. However, it should be noted that the mechanical property values for delivered bars and rods shall conform to the requirements irrespective of whether they are verified or not. SIST EN 10269:2014
Low temperature impact energy values are specified in Table 10 and Table 11. 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. 8.5 • Surface condition Slight surface imperfections, inherent in the production process, are permitted. The purchaser shall specify a surface quality class in accordance with EN 10221. 8.6 • Internal soundness The products shall be sound and free from defects that preclude their intended use. •• Where appropriate, requirements together with the conditions for their verification may be agreed at the time of enquiry and order. 9 Inspection 9.1 Types of inspection and inspection documents 9.1.1
• The compliance with the requirements of the order shall be checked for products in accordance with this European Standard by specific inspection. • The purchaser shall specify the required type of inspection document (3.1 or 3.2) in accordance with EN 10204. SIST EN 10269:2014

10.2.2.1 Round test pieces shall be prepared in accordance with Figure 1 for the tensile test at room temperature in accordance with EN ISO 6892-1 and, where applicable, for the tensile test at elevated temperature in accordance with EN ISO 6892-2. 10.2.2.2 Three longitudinal V-notched test pieces in accordance with Figure 1 and in accordance with EN ISO 148-1 shall be prepared for the impact test. 11 Test methods 11.1 •• Chemical analysis Unless otherwise agreed at the time of enquiry and order, the choice of a suitable physical or chemical analytical method for the product analysis shall be at the discretion of the manufacturer. In cases of dispute, the analysis shall be carried out by a laboratory approved by both parties. In this case, the analysis method to be used shall be agreed taking into account the relevant existing European Standards. The list of available European Standards is given in CEN/TR 10261. 11.2 Hardness test The Brinell hardness test shall be carried out in accordance with EN ISO 6506-1. 11.3 Tensile test at room temperature The tensile test at room temperature shall be carried out in accordance with EN ISO 6892-1 using a proportional test piece of gauge length Lo = 5,65 √So (So = cross-sectional area of the parallel length of the test piece).
