ASTM WK43674

    Revision of A240 / A240M - 13a Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications

    (What is a Work Item?)

    Active Standard: A240 / A240M - 14

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


    1. Rationale

    Some of the austenitic-ferritic grades do not contain a hardness limit in the Rockwell B column of Table 2. Footnote C to Table 2 limits hardness readings to Brinell or Rockwell B. Rockwell B is not a suitable measurement method for most austenitic-ferritic grades. Many of the austenitic-ferritic grades have a Rockwell C maximum with footnote J. I propose to add Rockwell C maximums to the austenitic-ferritic grades that do not currently have one so that Rockwell C readings will be acceptable.
