Carburization - facts and how to reduce the risk — …
Carburization is a phenomenon where carbon is incorporated into the material. Carbon bonds readily with chromium and chromium carbides will be formed, especially at the grain boundaries. This leads to erittlement of the material. The bonding of chromium to carbon results in chromium depletion in the matrix, reducing the resistance of the metal to oxidation and sulphidation.
