Description:
S31803 Tubing
Alloy 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 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.
