ASTM WK43318

    Revision of A216 / A216M - 12 Standard Specification for Steel Castings, Carbon, Suitable for Fusion Welding, for High-Temperature Service

    (What is a Work Item?)

    Active Standard: A216 / A216M - 14

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


    1. Rationale

    The S and P maximum levels in this specification were not representative of the materials that are actually produced today. At the maximum levels in the -08 edition of the specification, 0.04 P and 0.045 S, for all three grades, there are detrimental effects on 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. In view of that data analysis, the maximum permitted levels for P and S were reduced by approval of WK30941 to 0.035 for P and 0.035 for S. These are the levels in the current A216/A216M-12 edition. Committee A01.18 established a TG to review the data and its analysis, and to make recommendations for levels that do represent current production. The action to revise the maximum level for S from 0.035 to 0.030 for all three grades in this specification, as recommended by the A01.18 TG was on SCLB A01.18 (04-13) and received three negatives. At the November 12, 2013, meeting of A01.18, the negatives were deemed persuasive and the subcommittee suggested that the reduced sulfur limits be placed in a Supplementary Requirement that purchasers interested in the potential of improved toughness or corrosion resistance could cite.
