ASTM WK69224

    Revision of B850 - 98(2015) Standard Guide for Post-Coating Treatments of Steel for Reducing the Risk of Hydrogen Embrittlement

    (What is a Work Item?)

    Active Standard: B850 - 98(2015)

    Developed by Subcommittee: B08.02 | Committee B08 | Contact Staff Manager



    WK69224


    Keywords

    delayed brittle failure; heat treatment; hydrogen embrittlement; hydrogen embrittlement relief; hydrogen induced cracking; hydrogen stress cracking; post-treatments of steel ;;

    Rationale

    There are inconsistencies between specification requirements for embrittlement relief in some ASTM B08 documents and B849, more specifically what the threshold minimum tensile stress for materials susceptible to the risk of hydrogen embrittlement should be. In addition, Table 1, which lists specific embrittlement relief times and temperatures prior to plating according to material tensile stress, is confusing and difficult for users to interpret and determine what the correct stress relief condition should be specified. This table needs to be examined for simplification of use.
