Active Standard: A213 / A213M - 13
Modify the chemistry for UNS S31035. During the approval of two ASME code cases, it was requested by Section I, II, and VIII to restrict the chemistry more than was shown in the ASTM specifications based on the data from the three heats that were supplied for the code cases. The affected elements are P, Nb/Cb, N, Cu, and W. This change will align A213 with the code cases and eventually make incorporation of the code cases easier upon adoption of the revised ASTM standards.
