S32304 austenite-ferrite duplex steel pipe

UNS S32304 is a duplex stainless steel combining advantages of both austenitic and ferritic stainless steels. It offers high strength and superior corrosion resistance. Typically comprising approximately equal amounts of austenite and ferrite, the exact phase balance varies by grade.

This grade features high chromium content with reduced nickel and very low molybdenum, making it a cost-effective alternative to high-nickel alloys. Its performance includes:

Excellent resistance to stress corrosion cracking

High resistance to chloride and intergranular corrosion

Low welding sensitization

S32304 offers good physical properties, ease of fabrication, and superior weldability. Its resistance to pitting, crevice corrosion, and stress corrosion makes it suitable for harsh environments.
