ASTM WK44409

    Revision of A668 / A668M - 13e1 Standard Specification for Steel Forgings, Carbon and Alloy, for General Industrial Use

    (What is a Work Item?)

    Active Standard: A668 / A668M - 14

    Developed by Subcommittee: A01.06 | Committee A01 | Contact Staff Manager


    1. Rationale

    During the last revision of this specification, the test location for forgings in classes F, J, K, L, M and N was changed to 1/4Tc and 3.5 from all other quenched surfaces. This had the unintended consequence that some small forgings would require prolongations larger than Tc of the forging itself to meet the 3.5 set back from all other surfaces statement.
