ASTM WK46281

    Revision of A913 / A913M - 14 Standard Specification for High-Strength Low-Alloy Steel Shapes of Structural Quality, Produced by Quenching and Self-Tempering Process (QST)

    (What is a Work Item?)

    Active Standard: A913 / A913M - 15

    Developed by Subcommittee: A01.02 | Committee A01 | Contact Staff Manager


    1. Rationale

    The processing route for material produced using QST technology contained within the specification has been heretofore implicit to a large degree. This ballot recommends several additional controls to be placed into the specification to insure that material thus manufactured has the same integrity regardless of any subtle differences in how the product may be made. Specifically 1.Paragraph 4.1 is amended to more accurately describe the quenching process. 2.Table 1 is amended to provide for lower carbon and restricted use of intentionally added boron, both of which could be perceived as leading to improved weldability. Also phosphorus and columbium have been harmonized for all grades. 3.A supplementary requirement is added calling attention to weldability tests that may be conducted, the mode and frequency of which would be at the discretion of the manufacturer and the purchaser. 4.Lastly, Appendix X.1.2 has been rewritten for clarity and improved explanation of the QST process.
