Standard Specification for Castings, Iron-Chromium-Nickel, Corrosion Resistant, for Severe Service
2021
6
ASTM Vol.01.02 (2023)
This specification covers iron-chromium-nickel alloy stainless steel castings intended for particularly severe corrosive applications.
This specification requires post-weld heat treatment of all weld repairs affecting surfaces intended to be wetted by the corrosive medium. For applications for which post-weld heat treatment is not considered mandatory for retention of acceptable corrosion resistance, refer to Specification A743/A743M.
NOTE 1: For general corrosion-resistant alloy castings, reference should be made to Specification A743/A743M. For general heat-resistant alloy castings, reference should be made to Specification A297/A297M. For nickel-base alloy castings, refer to Specification A494/A494M.
