Product Description
UNS S32205 Duplex Stainless Steel Pipe ASTM A790 Seamless 2205 Grade
UNS S32205 is a widely used duplex stainless steel grade offering excellent combination of strength and corrosion resistance. With a microstructure of approximately 50% austenite and 50% ferrite, this material provides superior resistance to stress corrosion cracking, pitting, and crevice corrosion compared to standard austenitic stainless steels.
