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.
