ASTM A312 TP321H High Frequency Welded Finned Tubes CS Fins for Power Plant

ASTM A312 TP321H High Frequency Welded Finned Tubes CS Fins for Power Plant

ASTM A312 This specification covers seamless, straight-seam welded, and heavily cold worked welded austenitic stain less steel pipe intended for high-temperature and general corrosive service,such as power plants, boilers, superheaters, and heat exchangers.Wall thickness generally for pipes is average.

TP321H is a high-carbon variant of 321 for improved high-temperature strength. Austenitic stainless steel with Titanium can prevent carbide precipitation (sensitization) during welding or high-temperature service.

TP321H with a excellent creep resistance and oxidation resistance at elevated temperatures,and suitable for boiler tubes, superheaters, and reheaters in coal-fired, gas-fired, and nuclear power plants. And the material has good resistance to sulfidation, steam oxidation, and acidic environments,can resistant to intergranular corrosion due to titanium stabilization.
