Alloy seamless steel pipe is a kind of seamless steel pipe, and its performance is much higher than that of ordinary seamless steel pipe. Because alloy seamless steel pipe contains more Cr, its high temperature resistance, low temperature resistance, corrosion resistance is not comparable to other seamless steel pipe, so alloy steel pipe is widely used in petroleum, chemical, electric, boiler and other industries.

Alloy seamless steel pipes contain elements such as silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earths, etc.
