VACUUM CARBURIZING

Low torr(pressure) range vacuum carburizing for optimum case hardening. The benefits are wear resistant part surfaces, case depth uniformity, minimal distortion and bright, clean parts.

Low pressure Carburizing reduces part distortion & precise control of temperature & acetylene gas mixtures for optimal case depth.

Metallurgically Low torr range vacuum carburizing prevents microstructure surface intergranular Oxidation(IGO) and decarburization. The avoidance of IGO provides high integrity to the case. The presence or absence of carbides can be controlled according to the specification requirements. Additionally the process produces compressive residual stress for improved fatigue life. Metallurgical properties attained provide optimal surface & core hardness extending part performance & wear life.
