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 containing Cr, high temperature resistance, low temperature, corrosion-resistant performance of other non-pipe joints not match, so the more extensive use of alloy tube in the petroleum, aerospace, chemical, electric power, boiler, military, and other industries.
ASTM A335 is a standard specification for seamless ferritic alloy-steel pipe for high-temperature service. This specification covers nominal wall and minimum wall seamless chrome-molybdenum alloy-steel pipe intended for high-temperature service.
The grades of ASTM A335 include P5, P9, P11, P22, P91, and P92.
