S32304 3mm Cold Rolled Mild Steel Sheet Super Duplex Alloy 2304
Duplex Alloy 2304 Super Duplex Stainless Steel Sheets UNS S32304 Astm A240 overview
Duplex Alloy 2304 is a two-phase, ferritic, austenitic 23% chromium, 4% nickel, molybdenum-free duplex stainless steel. It has similar corrosion resistance properties to 316L. Furthemore, its mechanical properties 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 partcularly suitable for applications covering the -50 °C/+300 °C temperature range.
