ASTM WK42862

    Revision of A312 / A312M - 13a Standard Specification for Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes

    (What is a Work Item?)

    Active Standard: A312 / A312M - 14

    Developed by Subcommittee: A01.10 | Committee A01 | Contact Staff Manager



    WK42862

    1. Rationale

    Modify the chemistry for UNS S31035. During the approval of two ASME code cases, it was requested by Section I, II, and VIII to restrict the chemistry more than was shown in the ASTM specification based on the data from the three heats that were supplied for the code cases. The affected elements are P, Nb/Cb, N, Cu, and W. This change will align A312 with the code cases and eventually make incorporation of the code cases easier upon adoption of the revised ASTM standard.
