Carburizing is a themochemical treatment designed to increase the surface hardness of steel by spreading carbon on the surface.

The scope is to obtain a product with a very hard surface, resistant to wear and with a tenacious heart.

Carburizing is followed by quenching in oil, a phase that determines important structural transformations that improve the quality of the treated steel. A material with a high surface carbon content will therefore be obtained

All the metal parts that need wear resistance and considerable impact resistance are carburized, such as gear teeth, transmission parts, pinions, pins, bushings, camshafts.

All steels that have a carbon content of between 0.14% and 0.21% and alloy elements that do not exceed 3% can be carburized.

Carburization is made up of the following phases: heating, temperature homogenization, carburizing austenitization, carburization, surface carbon diffusion, diffusion cooling, quenching austenitization, oil quenching, stress relieving

  • high carbon content on the surface
  • wear resistance
