ASTM WK30783

    Work Item: ASTM WK30783 - Revision of A403 / A403M - 10 Standard Specification for Wrought Austenitic Stainless Steel Piping Fittings

    (What is a Work Item?)

    Active Standard: A403 / A403M - 13a

    Developed by Subcommittee: A01.22 | Committee A01 | Contact Staff Manager

    1. Rationale

    To revise the A403 fitting specification to downgrade the minimum strength requirement for WP321H to a minimum yield of 25 ksi and a minimum tensile of 70 ksi which would make it the same as the requirements for A312 seamless pipe in thicknesses greater than 3/8.
