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 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.
