Duplex stainless steels differ significantly from austenitic stainless steels in the following important respects:
1) Chemical composition
2) Mechanical properties
3) Formability
4) Weldability
5) Machinability

Twice design strength of austenitic and ferritic stainless steels
Wide range of corrosion resistance to match application
Good toughness down to minus 80 deg C but not genuine cryogenic applications
Particular resistance... Read More...
The attractive combination of high strength, wide range of corrosion resistance, moderate weldability would seem to offer great potential for increasing the market share of duplex stainless steels. However, it is important to und... Read More...
The range of duplex steels allows them to be matched for corrosion resistance with the austenitic and ferritic steel grades. There is no single measure of corrosion resistance. However, it is convenient to use the Pitting Resista... Read More...
To understand how duplex steels work, first compare the composition of two familiar steels austenitic 304 (1.4301) and ferritic 430 (1.4016).

The idea of duplex stainless steels dates back to the 1920s with the first cast being made at Avesta in Sweden in 1930. However, it is only in the last 30 years that duplex steels have begun to “take off” in a significant way... Read More...
Duplex stainless steels are very nomal now. They are being supplied by all the major stainless steel mills for a number of reasons:
Higher strength leading to weight saving
Greater corrosion resistance particularly str... Read More...
Having decided that you want to use stainless steel, it is usually quite straightforward to find the standard grades like 1.4301/1.4307 (304/304L) or 1.4401/1.4404 (316/316L).
This is an initial attempt to provide information on... Read More...
