products : { Duplex 2205 - Duplex 2205 stainless is a dual-phase stainless steel. }

Properties

Duplex 2205 stainless is a dual-phase stainless steel whose grain structure is about 45% ferritic and 55% austenitic, hence the name "duplex". With twice the mechanical strength and corrosion resistance of common austenitics, alloy 2205 offers some advantages over 316L and 317L:

* Lower coefficient of thermal expansion and a higher thermal conductivity
* Resists chloride stress corrosion cracking
* Pitting and crevice corrosion resistance
* Excellent choice for high chloride environments
* Lower cost than high alloyed austenitics

Applications

Industries taking advantage of the lower cost and higher mechanical properties of alloy 2205 include:

* Heat exchangers
* Marine construction
* Oil and gas industry
* Chemical processing
