Product Description

About products

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, zirconium, and other elements are strong carbide forming elements in steel. As long as there is sufficient carbon, their respective carbides can be formed under appropriate conditions. When carbon is lacking or at high temperatures, they enter the solid solution in an atomic state; Manganese, chromium, tungsten, and molybdenum are carbide forming elements, with some entering the solid solution in an atomic state and the other forming a replacement alloy cementite; Aluminum, copper, nickel, cobalt, and silicon are non carbide forming elements that generally exist in solid solutions in an atomic state.
