1.4574 UNS S31254 Special Alloy Steel Super Austenitic Stainless Steel

Alloy 1.4574 UNS S31254 Super Austenitic Stainless Steel

This grade of steel is a super austenitic stainless steel. They are high end stainless steel designed for impact toughness resistance to chloride crevice corrosion, stress corrosion cracking, and pitting. These are austenite with high content of nickel and chromium.

UNS S31254, a high molybdenum austenitic stainless steel specification. Its high molybdenum content combined with elements such as nickel and copper gives UNS S31254 excellent resistance to pitting and crevice corrosion. In acids containing halides it offers good resistance to uniform corrosion and is superior to other austenitic stainless steel grades.
