    Revision of A350 / A350M - 18 Standard Specification for Carbon and Low-Alloy Steel Forgings, Requiring Notch Toughness Testing for Piping Components

    (What is a Work Item?)

    Active Standard: A350 / A350M - 18

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



    carbon equivalent; pipe fittings, steel; piping applications; pressure containing parts; steel flanges; steel forgings, alloy; steel forgings, carbon; steel valves; temperature service applications, low;;


    Tensile and impact testing of flanges has not always given consistent results. For welding neck flanges the critical area generally is near the welding ends. Other types of flanges are also covered. To achieve consistency in getting similar results when testing by others, the location and orientation should be standardized. This new supplementary requirement is intended to provide consistency. The mandatory heat treatment and fine grain practice of the base specification shall apply.
