One of the most applied metal treatment processes is carburising. The main aim is to treat metal with this process is to harden it's surface layer. We are engaged in providing carburising service for metal, industrial gear and armor plate. The carbon diffuses into the metal being processed by heat treatment. This process starts by heating the metal in presence of carbon rich material/elements (CO, NaCN, BaCl2, etc.) for a specific carburising time period and at a specific temperature. As the metal is quickly cooled down through quenching process, the carbon content on metal's outer surface becomes hard. The hardness is achieved due to the making of martensite from austenite. Depending upon the workpiece to be carburised, the high carbon liquid, solid or gas is applied.
