Industrial Carburizing Furnace

Carburizing Process

The carburizing process, also known as case hardening, is the application of heat to diffuse carbon into the surface of the steel creating a thinner, harder layer of metal, known as the surface case, which strengthens the piece and prevents corrosion. While carburizing creates a tough outer case it still maintains the strength of the core at a lower hardness level. Carburization is commonly used after machining on low carbon steel parts and other alloys. The process of carburizing is performed in a heat treat furnace such as an integral quench furnace or pit furnace.
