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 304/316 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.

The chemical analysis of 2304 is optimized to obtain a typical 50 a / 50 g microstructure after solution annealing treatment at 950°/1050°C (1742°/1922°F).
The microstructure of 2304 duplex is very stable compared to molybdenum-containing duplex stainless steels. Intermetallic phases are present only after 10 hours holding time in the 750°/850°C (1382°/1562°F) temperature range. Copper additions to 2304 grade, when specified, increase the hardness of the steel after heat treatment in the 350°/500°C (662°/932°F) temperature range.
