Duplex Stainless Steel ASTM A815 UNS S31803 Fitting

Duplex Stainless Steel ASTM A815 UNS S31803 Fitting


ASTM A815 UNS S31803 duplex stainless steel fittings are forged from 2205 alloy with an austenite-ferrite duplex structure. Their yield strength is twice that of conventional austenitic stainless steel, while offering excellent resistance to chloride stress corrosion cracking and pitting and crevice corrosion (PREN ≥ 33).


These fittings are designed to provide high-strength, lightweight, and corrosion-resistant connection solutions for piping systems in harsh environments such as chemical, oil and gas, and offshore engineering.
