    (What is a Work Item?)

    Active Standard: A240 / A240M - 15a

    Developed by Subcommittee: A01.17 | Committee A01 | Contact Staff Manager


    1. Rationale

    A user has requested addition of a new grade, 317CU, of a nominal composition of 18 Cr- 16 Ni- 4.5 Cu- 3.5 Mo- N. The grade designation, 317CU, is temporary, and will be replaced by a UNS Number when one is issued. Request letters from a user and a data package supporting the request have been provided. The letter and the required data are appended to the ballot item. A parallel item to add the grade to A480 is not required, because this new grade shares the heat treatment requirements for All Cr-Ni steels except as listed below in the first line of Table A1.2 of A480/A480M.
