Carburizing of Bearings


This is most commonly used surface hardening process for low carbon steels. Carburizing is a case hardening process that introduces carbon into a solid ferrous alloy. Metal is heated in carbon rich atmosphere above transformation temperature for pre decided time. After carburizing, parts are quenched to harden the surface carburizing layer.

Case depth from 0.3 mm up to 3 mm can be provided. Please check with us for higher case depths.
