Seamless alloy steel tube is a kind of seamless steel tube, its performance is much higher than the general seamless steel tube, because this kind of steel tube contains Cr more, its high temperature resistance, low temperature resistance, corrosion resistance performance is not comparable to other seamless steel tube, so alloy tube in petroleum, chemical industry, electric power, boiler and other industries use more widely.
Seamless alloy steel tube contains elements such as silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth and so on.
Seamless Steel Tube is a long strip of Steel with a hollow section and no seams around it.Steel pipe has a hollow section, a large number of pipe used for conveying fluid, such as oil, natural gas, gas, water and some solid materials pipeline.Seamless alloy steel tube and round steel, such as solid steel, in the bending and torsion strength at the same time, the weight is lighter, is an economic section of steel, widely used in the manufacture of structural parts and mechanical parts, such as oil transport, stair handrail, bicycle frame and construction use of steel scaffolding.Using seamless alloy steel tube to make ring parts can improve the material utilization rate, simplify the manufacturing process, save material and processing time, such as rolling bearing ring, jack sleeve, etc.Alloy seamless steel tube or a variety of conventional weapons indispensable material, gun barrel, barrel, and so on to be made of steel tube.In addition, the circular section under internal or external radial pressure, stress is more uniform, so most of the seamless alloy steel tube is a circular tube.
