ASTM WK45711

    Revision of A312 / A312M - 14 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



    WK45711

    1. Rationale

    The nickel content for UNS 30451 (TP304N) is incorrect at 8.0-18.0. It needs to be corrected to 8.0-11.0 to align with other product specifications and ASTM A959. Also there is a redundancy between the 5.2 and 6.2, which both address heat treatment requirements.
