General Properties

Duplex 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel whose structure is a balance of ferritic and austenitic. It has general corrosion resistance similar or better than Alloys 304L and 316L but with yield strength nearly double that of austenitic stainless steels. Its duplex microstructure and low nickel and high chromium contents also allows Duplex 2304 to demonstrate improved stress corrosion resistant properties compared to 304 and 316. It is typically suitable for all applications in the -58^oF to 572^oF (-50^oC to 300^oC) temperature range and is designed to feature high mechanical strength, good weldability, good corrosion resistance, high resistance to stress corrosion cracking, good machinability, low thermal expansion, good fatigue properties, high thermal conductivity, and easy fabrication.

Specifications: UNS S32304

Applications:

Duplex 2304 is generally used in the same applications in which Alloys 304 and 316L are used. Some examples of these applications include:

Chloride containing environments
Welded pipe systems within the Pulp and Paper, Chemical and Petrochemical, and Water Treatment industries
Transportations
Heat exchanger tubes
Architecture, building, construction
Pressure vessels
Caustic solutions, organic acids
Food industry
