ASTM A213

ASTM A213 T9, T11, T22, T91 Alloy and Stainless Tubing

ASTM A213 tubing has been widely used in high temperature services especially for the boiler and superheater. Tube material could be in alloy steel and stainless steel, and manufactured in seamless of hot rolled or cold drawn. so this pipe usually used in very important places and the price is much higher than normal carbon pipes. Common grades are T9, T11, T12, T21, T22, T91 and stainless grades in TP304 or TP316.
