controlled atmosphere vacuum quenching furnace for die alloy

Vacuum furnace - Wikipedia

A vacuum furnace is a type of furnace in which the product in the furnace is surrounded by a This inert gas can be pressurized to two times atmosphere or more, then a vacuum furnace is commonly used for the heat treatment of steel alloys. Once the workload is properly "cased", the metal is quenched using oil or high
