ASTM A335 T12 Seamless ferritic alloy-steel pipe for high-temperature service
ASTM A213 T12 is part of ASTM A213 Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, Heat-Exchanger Tubes.
Alloy steel pipe is a kind of seamless steel pipe, its performance is much higher than the general seamless steel pipe because this steel pipe inside contains Cr, high-temperature resistance, low temperature, the corrosion-resistant performance of other non-pipe joints does not match, so the more extensive use of alloy tube in the petroleum, aerospace, chemical, electric power, boiler, military, and other industries.
The alloy steel pipe adopts high-quality carbon steel, alloy structural steel and stainless & heat resisting steel as raw material through hot rolling or cold drawing to be made.
