    Rationale

    The Work Order request is to add a new alloy to the Specification. The alloy is referred to UNS No. S34752 with slightly higher mechanical properties and allowable stress values at high temperature. The alloy is backed by UOP for refinery and high temperature applications. The only difference in chemistry is added boron 0.001-0.005 and a slightly higher Nitrogen 0.06-0.12 (from 0.06-0.10) in UNS No. S34752
