A213 / SA213 Seamless Carbon Steel Tubing , T11 Heat Exchanger And Condenser Tubes
Alloy Steel ASTM A213 T11 Tubes are Ferritic alloy steel tubes that are available in multiple grades. Elements such as manganese, chromium, molybdenum, carbon, and sulfur are considered to form these grades of tubes. These tubes are generally convenient for flanging, bending and for fusion welding. These tubes may be cold drawn or hot finished throughout the finishing heat treatment procedure. The creep resistance of the tube is increased due to molybdenum content. These tubes possess superior ductility, hardness and tensile strength in tough climatic circumstances. Evermore these have great sturdiness, durability, and resistance consistency.
Product Standard: GB/T8163, DIN17175,SAME SA106/SA179/SA210 A1,C/SA213/SA335
Main steel grades: T5,T9,T11,T12,T22,T91
Application: For boiler and superheater, conveying water, oil, gas and other common fluids
