Product Description

About products

Alloy steel refers to the addition of other alloy elements in steel besides iron and carbon, which is called alloy steel. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel. According to the different added elements and adopting appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance and non-magnetism can be obtained.
The main alloying elements of alloy steel include silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth, etc.
Among them, vanadium, titanium, niobium and zirconium are strong carbide-forming elements in steel. As long as there is enough carbon, they can form their own carbides under appropriate conditions. When carbon is lacking or at high temperature, they enter the solid solution in atomic state; Manganese, chromium, tungsten and molybdenum are carbide-forming elements, one part of which enters the solid solution in atomic state, and the other part forms replacement alloy cementite; Aluminum, copper, nickel, cobalt, silicon and other elements do not form carbides and generally exist in solid solution in atomic state.
