| High Light | Stainless Steel Round Pipe UNS S32205 ，Stainless Steel Round Pipe Seamless ，2205 Stainless Steel Pipe Welded | ||
2205 stainless steel round tube is a high-strength, highly corrosion-resistant specialty pipe material. Its microstructure consists of approximately 50% ferrite and 50% austenite in a duplex configuration. This unique microstructure gives it nearly twice the yield strength of ordinary stainless steel, while also exhibiting excellent resistance to stress corrosion cracking in chloride ion environments.
Compared to 304 and 316L austenitic stainless steels, 2205 can withstand higher pressures with the same wall thickness, or allows for thinner wall thicknesses to achieve weight reduction and cost savings, making it an ideal material for industries such as petrochemicals, marine engineering, and papermaking.
