Carburizing

Carburizing consists of the diffusion of carbon in the outer layer of the material. For this process we need high temperature (over AC3),the diffusion process is accelerated by temperature ,and a long holding time(depending of the carburizing layer we want to obtain).This process takes place in controlled atmosphere based on high carbon potential (endogas + methane, endogas + propane, N2 + methanol + propane). Following the carburizing comes hardening and low temperature tempering. The obtained structure is a high carbon content martensite with high hardness and good mechanical properties, even for low carbon steels.

The carburizing process can take place in:
