ASTM A213 / ASME SA213 TP310S Stainless Steel Seamless Tube Superheater Application
ASTM A213 TP310S seamless tubes are made from austenitic stainless steel 25Cr-20Ni, which is higher in chromium and nickel. They have a very high resistance to corrosion and oxidation at elevated temperature. Thus, TP310S seamless tubing can be used for the construction of boilers, superheaters, and heat exchangers working at elevated temperatures in moderately oxidizing conditions.
