Austenitic steel ASME SA213 · TP310H

Short Description:

The high-carbon high-chromium-nickel austenitic stainless steel is mainly used in power plants, boilers, superheaters, reheaters, and petrochemical refineries. Specially designed for high-temperature service requiring superior creep rupture strength, this grade provides exceptional resistance to oxidation, carburization, and thermal degradation at continuous operating temperatures up to 1100°C. Furthermore, this grade is suitable for TIG, MAG and manual arc welding procedures.
