Lean Duplex S32304

Lean Duplex S32304





The alloy lean duplex 2304 has similar corrosion resistance properties 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.
