Stainless Steel Grade Duplex 2304 (UNS S32304)
Stainless steel grade Duplex 2304 is a duplex stainless steel type with a structure that is a balance of ferritic and austenitic. It has high strength and toughness, resistance to stress corrosion cracking, high thermal conductivity, low thermal expansion, and easy fabrication. It is recommended that this steel is not used in areas where the steel would be exposed to temperatures over 1058°C (570°F) for prolonged periods.
