ASTM ASME 201 Stainless Steel Pipes & Tubes are manufactured from austenitic chromium-nickel-manganese (Cr-Ni-Mn) alloy 201 stainless steel, offering cost-effective corrosion resistance and moderate strength. Compliant with ASTM A213 (seamless), A269 (welded), and A312 (seamless/welded) standards, they are suitable for high-temperature and corrosive environments. Typical applications include heat exchangers, boilers, condensers, and industrial piping systems. Key features include excellent formability, weldability, and oxidation resistance up to 870°C (1600°F). Available in annealed condition with a smooth surface finish, meeting dimensional tolerances per ASME B36.19.
