Tensile Strength Stainless Steel Round Bar S32205 With Corrosion Resistance

Duplex 2205 is a nitrogen enhanced duplex stainless steel that was developed to combat common
corrosion problems encountered with the 300 series stainless steels. “Duplex” describes a family of
stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless.
The structure of 2205 duplex stainless steel consists of austenite pools surrounded by a continuous
ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. Often referred
to as the work horse grade, 2205 is the most widely used grade in the duplex family of stainless
steels.
The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy
(stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of
fabrication and corrosion resistance).
Usage of 2205 Duplex stainless steel should be limited to temperatures below 600° F. Extended
elevated temperature exposure can embrittle 2205 stainless.
Corrosion Resistance
2205 duplex stainless steel is a cost effective solution for many applications where the 300 series
stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking
occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking.
The combination of chromium, molybdenum and nitrogen convey the good resistance of 2205 to
chloride pitting and crevice corrosion. This resistance is extremely important for services such as
marine environments, brackish water, bleaching operations, closed loop water systems and some
food processing applications. The high chromium, molybdenum and nitrogen contents of 2205
provide corrosion resistance superior to common stainless steels, such as, 316L and 317L in
most environments.
