Čelični otkovci za opremu pod pritiskom – Deo 5: Martenzitni, austenitni i austenitno-feritni nerđajući čelici

Steel forgings for pressure purposes - Part 5: Martensitic, austenitic and austenitic-ferritic stainless steels

Ovim evropskim standardom se utvrđuju tehnički zahtevi za isporuku otkovaka za opremu pod pritiskom, izrađenih od nerđajućih čelika, uključujući čelike koji su otporni prema prelomu usled trajne statičke deformacije. Utvrđuju se hemijski sastav i mehaničke osobine. Opšte informacije o tehničkim zahtevima za isporuku date su u EN 10021.

This European Standard specifies the technical delivery conditions for forgings for pressure purposes, made of stainless steels, including creep resisting steels. Chemical composition and mechanical properties are specified. NOTE Once this standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this 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 2014/68/EU are satisfied, needs to be done. The series EN 10222-1 to EN 10222−5 is structured so that the data related to different materials is in the part allocated for that material. The presumption of conformity to the Essential Safety Requirements of Directive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5. General information on technical delivery conditions is given in EN 10021.
