ASTM WK43113

    Work Item: ASTM WK43113 - Revision of A351 / A351M - 13a Standard Specification for Castings, Austenitic, for Pressure-Containing Parts

    (What is a Work Item?)

    Active Standard: A351 / A351M - 13a

    Developed by Subcommittee: A01.18 | Committee A01 | Contact Staff Manager



    1. Rationale

    S and P levels in this specification are not representative of the materials that are actually produced today. At these maximum levels there are detrimental effects on material properties such as toughness and corrosion resistance. The Steel Founders Society of America (SFSA) collected a large amount of data from sand and investment casting producers and subjected it to rigorous statistical analysis. Committee A01.18 established a TG to review the data and make recommendations for levels that do represent current production. This action revises the S and/or P limits in A351/A351M for grades CF3, CF3M, CF8C, CK20, CN7M, CG8M, CT15C, CK3MCuN and CG3M based on this data and the TG recommendations.
