Alloy steel pipe is a kind of seamless steel pipe, its performance is much higher than the average seamless steel pipe, because this steel pipe contains more Cr, its high temperature, low temperature, corrosion resistance is the performance of other seamless steel pipe than On, Alloy Steel Pipe and Tube so the alloy steel pipe in the oil, aerospace, chemical, power, boilers, military and other industries more widely used.

Alloy alloy steel alloy mainly chromium (Cr) and molybdenum (Mo); in the heat-resistant steel by adding chromium is the main purpose is to improve the steel's antioxidant properties and corrosion resistance. Therefore, chromium is the main element in heat-resistant steel, Alloy Steel Pipe and Tube with its different content, the boiler is divided into four kinds of heat-resistant steel, Cr = 1% to 5% for the first; Cr = 8% to 9% for the second Cr = 11% to 13% for the third; Cr 鈮 18% for the fourth, respectively, for the different temperature of the compression parts of the chromium alone to improve the thermal strength of the contribution is not, and other Alloying elements. Alloy Steel Pipe and Tube Chromium has the effect of preventing graphitization. Molybdenum can improve the hardenability of steel, but its effect is not as good as C and Cr. Molybdenum can improve the thermal strength of steel, when the content of 1% to 2%, the lasting strength significantly improved. Separate molybdenum-containing alloy steels have been rarely used as boiler pressurized parts.
