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 this kind of steel pipe contains more CR Its high temperature resistance, low temperature resistance and corrosion resistance are unmatched by other seamless steel pipes, so alloy pipes are widely used in petroleum, chemical industry, electric power, boiler and other industries. Alloy seamless steel pipe contains elements such as silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth, etc.
