Duplex Stainless Steel - Part 1 - TWI
In addition to the improved corrosion resistance compared with the 300 series stainless steels duplex steels also have higher strength. For example, a Type 304 stainless steel has a 0.2% proof strength in the region of 280N/mm 2, a 22%Cr duplex stainless steel a minimum 0.2% proof strength of some 450N/mm 2 and a superduplex grade a minimum of 550N/mm 2.

Based primarily on microstructure, five stainless steel types are recognized: ferritic, martensitic, austenitic, duplex and precipitation-hardening. The major problem in ferritic stainless steels is the tendency to embrittlement, aggravated by various causes. During welding, control of heat input is essential and, in some cases, also a postweld heat treatment.
