Description:
S32304(2304) is a 22.5% Cr, 3% Nickel, Mo free duplex stainless steel. The alloy 2304 has a corrosion resistance 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 are subject to restrictions, particularly for welded structures. With its duplex microstructure, low nickel and high chromium contents, the alloy has improved stress corrosion resistance properties compared to 304 and 316. An enhanced version with a PREN ≥ 28 is also available on request.
