Industrial Carburizing Furnace

Carburizing Process

The carburizing process 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 also known as case hardening and is performed in a heat treat furnace such as an integral quench furnace or pit furnace.
