Vacuum gas quenching furnace use high pressure inert gas for the quick cooling of workpieces after vacuum heating, which is mainly used for the quenching of high hardenability steel,like high alloy steel, High speed steel,mold steel etc, most popular material like H13,D2, Cr12MoV. It can also be used for other vacuum heat treatment and vacuum brazing, sintering etc.
Main functions
Control rate heating in vacuum or inert gas atmosphere;
Convective heating in inert gas atmosphere;
Partial pressure control;
High pressure gas quenching;
Isothermal quenching;
