What is UNS S31254 Stainless Steel?

UNS S31254, or 254 SMO, is a super austenitic stainless steel with a high content of molybdenum (6%) and nitrogen, along with chromium and nickel to offer better pitting, crevice corrosion, and chloride stress corrosion cracking resistance.

This steel alloy was designed to perform in harsh conditions where other stainless steels such as 316L and 317L can't function. It gives an ideal balance of strength, corrosion resistance, and weldability, hence a suitable material for demanding applications.
