ASTM WK41609

    Revision of A312 / A312M - 12a Standard Specification for Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes

    (What is a Work Item?)

    Active Standard: A312 / A312M - 14b

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


    1. Rationale

    The minimum Ti calculation for S32100 (321) in ASTM A312 is 5XC. The same calculation for minimum Ti for the same grade in ASTM A240 is 5(C+N). When ASTM A240 was changed from a minimum Ti of 5xC to 5(C+N)in S32100 it was determined that the latter calculation more accurately ensured stabilization. Hence, we propose to change the N minimum in ASTM A312 to 5(C+N).
