    Revision of A268 / A268M - 10(2016) Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service

    (What is a Work Item?)

    Active Standard: A268 / A268M - 10(2016)

    Developed by Subcommittee: A01.10 | Committee A01 | Contact Staff Manager



    WK69879


    Keywords

    ferritic stainless steel; seamless steel tube; stainless steel tube; steel tube; welded steel tube;;

    Rationale

    In the scope of A268, a statement Grade TP439 is used primarily for hot-water tank service and does not require post-weld heat treatment to prevent attack of the heat affected zone. which is being interpreted that the tubing does not require a heat treatment. Section 7 requires heat treatment for all alloys in the specification. Some producers are interpreting that a heat treatment is not required for that grade only. The purpose of this item is to remove the statement in the scope.
