ASTM WK46183

    Revision of A182 / A182M - 14 Standard Specification for Forged or Rolled Alloy and Stainless Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service

    (What is a Work Item?)

    Active Standard: A182 / A182M - 14a

    Developed by Subcommittee: A01.22 | Committee A01 | Contact Staff Manager



    WK46183

    1. Rationale

    An inquiry from a user questioned the validity of the nominal compositions in the Grade column of Table 2 and pointed out that many of the entries did not reflect the actual required compositions in other columns in the table. The A01.22.03 section recommended that, to eliminate the confusion, the Grade column should be deleted and the heading of the Identification Symbol column should be changed to: Grade/Identification Symbol. The section also determined that it was important to be consistent in the use of F-numbers, rather than UNS numbers in the Grade columns of Tables 1, 2, 3, and 4, so the listings for S31727 and S32053 are being corrected to be the next available F-numbers.
