S31803 specification :
S31803 duplex stainless steel is chromium from 21%, 21% nitrogen and 4.5% molybdenum nickel alloy consisting of duplex stainless steel.It has high strength, good impact toughness and good overall and partial stress corrosion resistance.S31803 duplex stainless steel yield strength is twice that of austenitic stainless steel, this feature enables designers when designing products lose weight, make this alloy is better than 316 317 L has a price advantage.This alloy is particularly suited to - + 50 ° F / 600 ° F temperature range.
