Scope

Main technical content: This standard specifies the ordering content, classification, dimensions, appearance, weight, and allowable deviations of austenitic-ferritic duplex stainless steel round billets; technical requirements; test methods; inspection rules; packaging; marking; and quality certificates. This standard applies to the manufacture of austenitic-ferritic duplex stainless steel tubes with a diameter not exceeding 550mm, and also applies to forged billets with a diameter greater than 550mm. The design and compilation of the "Austenitic-Ferritic Duplex Stainless Steel Round Billets" standard are mainly problem- and demand-oriented, and are based on the actual needs of austenitic-ferritic duplex stainless steel tube production. It further defines technical requirements for product grades, ovality, bending, end portions, surface quality, and other technical indicators, and enhances the guiding significance of standards in specialized fields.
