UNS S32001
UNS S32001
Description
S32001 stainless steel is a low alloyed lean duplex stainless steel developed with increased Cr, Mo and N content to achieve a PRE of ≥24. The microstructure consists of a phase balance of approximately 50% ferrite and 50% austenite that provides much higher yield strength than AISI 304 and AISI 316. Also, it exhibits good formability and corrosion resistance. However, it has a fairly low embodied energy among wrought duplex stainless steels and a moderately low base cost and a fairly low tensile strength.

Additional Properties
Corrosion Resistance: The steel exhibits good corrosion resistance, better than AISI 304 austenitic and can even be compared with 316 in most cases.
Stress Corrosion Cracking: The steel is more resistant to stress corrosion cracking than austenitic stainless steels.
Atmospheric Corrosion: The steel is more resistant to atmospheric corrosion than AISI 304, being similar to AISI 316.
Welding: The steel can be welded using most of the conventional welding methods, such as MMA/SMAW, TIG, MIG, SAW, FCAW, laser, etc.
Heat Treatment: Solution annealing at 1020-1100 °C followed by water quenching.
Weldability: Very good.
