UNS S32304 - EN 1.4362

Essential details
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 exposes to temperatures over 1058°C (570°F) for prolonged periods.

Typical Applications:

- Bridges

- Storage tanks

- Water heaters

- Heat exchangers

- Pressure vessels

- Feedwater tubes

- Heat exchangers

- Flue-gas cleaning

- Seawater systems

- Desalination plants

- Parts for structural design

- Rotors, impellers and shafts
