Super Austenitic Stainless Steel

These highly alloyed grades are fully austenitic and provide excellent corrosion resistance, especially to chloride, pitting, crevice, and stress corrosion cracking. These alloys may be a lower cost alternative to nickel base alloys depending on the application.

Applications Where good resistance to chloride pitting corrosion and stress corrosion cracking
Limitations Lower strength, prone to hot-shortness
Typical Uses Desalination applications
Machinability Fair
Weldability Fair, special precautions are necessary along with post-weld heat treatment
Corrosion Resistance Very good
