Suppliers are working hard to make
sure their heat treating equipment is controllable, repeatable and efficient,
and manufacturers continue to incorporate technology that gives heat treaters and their customers more information about what's going on inside the magic box.
High demands for cost-effectiveness and improved product quality can be achieved via a new low pressure
carburizing process with high pressure gas quenching. Up to 50% of the heat treatment time can be saved. Furthermore, the distortion of the gear parts could be reduced because of gas quenching, and grinding costs could be saved. This article gives an overview of the principles of the process technology and the required furnace technology. Also, some examples of practical applications
