Alloy Steel Seamless Tube ASTM A213 T11 T22 Heat Exchanger Tube High Pressure Boiler Tube
ASTM A213/ASME SA213 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.
Heat treatment types for common grades
a. For grades T9, T11, T22, heat treatment methods are full or isothermal anneal, normalize and temper. (For conditions in later option, tempering temperature for T9 and T22 is above 675℃, T11 is above 650℃.)
b. For grades T91, T92, shall be normalize and temper, where normalizing shall be above 1040℃, tempering shall be above 730℃. As the delivery conditions.
SA213/A213 T11 is a Seamless ferritic and austenitic alloy steel Boiler Tube
