S32205、S31803（1.4462）










Summary

Alloy S32205 S31803 is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness.
Alloy S32205 S31803 provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steel in almost all corrosive media. It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic. 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 austenitic alloy ease of fabrication and corrosion resistance.
Duplex S32205 S31803 is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steel. “Duplex” describes a family of stainless steel that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless steel. The structure of 2205 duplex stainless steel consists of austenitic pools surrounded by a continuous ferritic phase. In the annealing condition, 2205 contains approximately 40-50% ferrite. Ofen referred to as the work horse grade, 2205 is the most widely used grade in the duplex stainless steel tube.
