Alloy 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel. The Alloy 2304 has corrosion resistance properties similar to 316L. Furthermore, its mechanical properties, i.e., yield strength, are twice those of 304L/316L austenitic grades. This allows the designer to save weight, particularly for properly designed pressure vessel applications.
The alloy is particularly suitable for applications covering the -50°C/+300°C (-58°F/572°F) temperature range. Lower temperatures may also be considered but need some restrictions, particularly for welded structures.
With its duplex microstructure and low nickel and high chromium contents, the alloy has improved stress corrosion resistance properties compared to 304 and 316 austenitic grades.
2304 Duplex Stainless Steel 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
Equivalent Standards of 2304 Duplex Stainless Steel:
ASTM/ASME: UNS S32304
EURONORM: FeMi35Cr20Cu4Mo2
DIN: 2.4660
