Alloy Steel Seamless Tubes for Power Plant Boiler and Heat Exchanger


Detailed Product Description



Alloy steel tubes is a kind of steel alloyed tube with other elements in amounts
of between 1 and 50% by weight to improve its mechanical properties.Alloying
elements are added to achieve certain properties in the material. As a guideline,
alloying elements are added in lower percentages (less than 5%) to increase
strength or harden ability or in larger percentages (over 5%) to achieve special
properties, such as corrosion resistance or extreme temperature stability.
Main Materials:
ASTM 213(Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes)
ASTM A213 T5, T9, T11, T22, T23, T91, T92
ASTM A335 (Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service)
ASTM A335 P5, P9, P11, P22, P91, P92

ASTM A/ASME SA 213 specification pipes are available in grades including T5, T9, T11, T22, T23, T91, T92. ASTM A/ASME SA335 Grade P5, P9, P11, P22, P91, P92. Alloy steel tubes are generally available in stock with OD sizes in all standard sizes and thicknesses.On demand, we can offer our customers with high quality alloy steel pipes and tubes with black painting, anti-corrosion oil and galvanised finish.
