Duplex Stainless Steels have increased in popularity of the past decade, this is due to their outstanding features:
-Higher strength leading to weight saving
-Greater corrosion resistance particularly stress corrosion cracking
-Better price stability
-Lower price
History of Duplex Stainless Steels:
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. This is mainly due to advances in steelmaking techniques particularly with respect to control of nitrogen content.
Summary of Characteristics:
-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 to stress corrosion cracking
-Weldable with care in thick sections
-More difficult to form and machine than austenitics
-Restricted to 300 deg C maximum

What are Super Duplex Stainless Steels? Super duplex steels from NeoNickel are formed from an approximately 50/50 mixture of austenitic and ferritic steel and are often also known as austenitic-ferritic stainless steels. Super duplex stainless steels combine the best attributes of both austenitic and ferritic stainless steels and provide outstanding strength and ductility with excellent corrosion resistance – giving them an advantage over 300 and 400 series stainless steels.
Super duplex stainless steels are generally more complex, more highly alloyed materials with PREn (Pitting Resistance Equivalent number) = 40.0 and offer even higher strength and corrosion resistance than duplex stainless steels making them suitable for very demanding applications such as offshore marine engineering.
Super duplex stainless steels are available from NeoNickel and can be released to various specifications in a variety of forms. If you’re looking for super duplex stainless steels then you’ve come to the right place!.
