Carburizing

Carburizing is a heat treatment process used to strengthen steel by adding carbon to its surface. The steel is heated in an environment rich in carbon, such as a carbon-rich gas or solid material, which allows carbon atoms to diffuse into the outer layer. This creates a hard, wear-resistant outer shell while maintaining a softer, more ductile interior. The process enhances the steel's durability and performance in applications like gears, shafts, and bearings, where surface hardness is essential without compromising overall toughness.
