Carburizing furnaces

The Kanthal® program includes products for many types of carburizing furnaces. Our products are designed for extremely high temperatures and carbon potentials, contributing to maximized heat flux and reduction of process time, higher reliability and longer service life.

Carburization of steel products creates a harder outer surface through the application of heat which diffuses the carbon in the material. This creates a thinner stronger outer layer, also known as case hardening.

The Kanthal® offering for carbuization allows for precise control of temperature with electrical heating elements. The harsh atmospheres of the furnaces often lead to shorter lifetimes of heating elements and requiring more downtime to fix.

However, the introduction of Kanthal® APM is the choice of many in the industry for longer life at temperatures up to 1050°C (1920°F).
