ABSTRACT:
A large, austenitic, non-magnetic, stainless steel, alloy article which has been significantly warm worked between about 1500 F. and 1650 F. but not subsequently annealed, which has a 0.2% yield strength of at least about 90 ksi, and which, when formed into a U-bend, does not undergo stress corrosion cracking within about 700 hours in boiling saturated aqueous sodium chloride containing 2 weight percent (w/o) ammonium bisulfite. The alloy of the article consists essentially of about:
