This series uses a surface hardening method, which improves wear resistance by hardening the work surface while retaining softness within the work to allow energy loaded on the surface to be absorbed internally. This method is used in carburizing and quenching, carbonitriding and gas soft nitriding.

SAD - Small gas carburizing furnace
