Vacuum Carburizing

Processing Advantages

Solar Atmospheres offers "Low Torr Range Vacuum Carburizing"(also known as low pressure carburizing) for optimum case hardening of your parts. The benefits are wear resistant part surfaces with case depth uniformity, maximum case integrity, minimal distortion and bright, clean parts.
Solar carburizes in a single chamber with a newly developed insitu, gas pressure quenching system. The advantages include reduction in part distortion and precise temperature control, optimal case depths with acetylene gas mixtures.  Single chamber carburizing means less part handling for cost effective processing.
Metallurgically, "Low Torr Range Vacuum Carburizing" prevents surface intergranular oxidation (IGO) and decarburization. The avoidance of IGO provides high case integrity for improved wear life compared to traditional carburizing.  Additionally, the presence or absence of carbides can be controlled according to specification requirements. The process also produces compressive residual stress for improved fatigue life. The result - metallurgical properties that provide optimal surface and core hardness for the most advantageous part performance and wear life.
