Hardening is the quenching process that is done through vacuum champer
By the lateste Technology of Schmetz, workpiece can avoid risk of bend in case
workpiece is long and thin.
Our furnace can stand for 10 bar pressure of Nitrogen. This result in deep hardness from surface.
Besides, tempering also can be done directly without open the chamber again in case of special requirement.
It provide you with clean and nice surface.
