Standard Specification for
Castings, Iron-Chromium-Nickel,
Corrosion Resistant, for Severe Service
AASHTO Designation: M 285M/M 285-07
ASTM Designation: A 744/A 744M-06
SCOPE
1.1.This specification covers iron-chromium-nickel alloy, stainless steel castings intended for particularly severe corrosive applications.
1.2.This specification requires postweld heat-treatment of all weld repairs affecting surfaces intended to be wetted by the corrosive medium.
For applications for which postweld heat treatment is not considered mandatory for retention of acceptable corrosion resistance, refer to M l 63M/M 163.
Note 1-For general corrosion-resistant alloy castings, reference should be made to
M 163MIM 163. For general heat-resistant alloy castings, reference should be made to
ASTM A 297/A 297M. For nickel-base alloy castings, refer to ASTM A 494/A 494M.
