ASTM WK46158

    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 - 15

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


    1. Rationale

    Supplement S2.1 permits macro etch testing to reveal grain flow. The method of testing is to be done to Method E381 (Standady Method of Macroetch Testing Steel Bars, Billets Blooms and Forgings), however grain flow evaluation is beyond the scope of this method. It is proposed that Method E381 be replaced with Method E340 (Standardy Test Method for Macroetching of Metals and Alloys) which does include grain flow evaluation within its scope.
