BAOHUI STEEL produces ASTM A789 UNS S31803 Duplex 2205 Tube, a premium ferritic-austenitic stainless steel that combines the best properties of both microstructures. With a mixed structure of approximately 50% ferrite and 50% austenite, Duplex 2205 offers nearly double the yield strength of conventional 300-series stainless steels along with exceptional resistance to stress corrosion cracking, particularly in chloride-containing environments. Peb cov hlab yog tsim kom tau cov qauv zoo tshaj plaws rau cov ntawv thov.
