In an atmosphere which an enriched gas such as butane/propane is added to an endothermic reformed gas (RX Gas) that mainly composed of CO, N2, H2 inside the furnace, the steel material was heated to approximately 900-940˚C and carburized by penetrating carbon on the material surface, then hardened by lowering the temperature.

A hard and tough carburized hardened layer can be formed on the surface, and since the inside of treated product is moderately soft structure, high hardness can be obtained on the surface while securing high impact strength as a part, and it has excellent wear resistance and fatigue resistance, and this Heat Treatment is widely applied to various kind of machines parts including automobile parts and motorcycle parts.

We have two kinds of Gas Carburizing furnace, batch type and mini continuous type.
