Key advantages of ASTM A312 TP321H stainless steel cold finished pipe
ASTM A312 TP321H stainless steel pipe is an austenitic structure, non-magnetic and corrosion-resistant after welding, and can resist stress corrosion caused by organic acids and chlorides.
ASTM A312 TP321H stainless steel bright annealed pipe is annealed in a protective atmosphere, with no oxide scale on the surface and a roughness of Ra≤0.8μm. Annealing treatment makes the internal structure of the pipe uniform, with a ductility of more than 40%, which is convenient for deep processing such as complex bending and flaring. The creep rupture strength at 700-900℃ is 15% higher than that of TP321, which is suitable for supercritical power station boiler pipes and aircraft engine exhaust pipes.
