Alloy 6Mo UNS S31254

6 Mo (UNS S31254) is a super austenitic stainless steel with a high level of molybdenum and nitrogen, providing high resistance to pitting and crevice corrosion as well as high strength compared with conventional austenitic stainless steels such as 316L. The alloy can provide excellent resistance to stress corrosion cracking allowing tube cold forming and may be used without the necessity to re-anneal at testing up to 120°C.
