Forged Fittings ASTM A182 F51 UNS S31803 Duplex Stainless Steel Coupling B16.11
ASTM A182 F51(UNS S31803) is a duplex stainless steel which has a high resistance to pitting, stress and crevice corrosion, and it also has high mechanical strength and good weldability. ASTM A182 F51(UNS S31803) Duplex Stainless Steel Fittings have better corrosion resistance. They are suitable for the temperature that is above 300ºC because they usually suffer precipitations of brittle micro constituents.
