JGEF Furnace of China shipped six furnaces to a Japanese heat-treating company. Four horizontal, front-loading nitriding furnaces are designed specifically for precision gas nitriding in a retort style with vacuum purge. This gas nitriding method precisely controls the case depth and nitride layer formation (including white layer) to achieve high surface hardness, improved wear resistance and longer fatigue life.

Two horizontal tempering furnaces are designed to temper workloads after hardening. These furnaces, which are capable of achieving ±10°F at temperatures of 400-1300°F through nine points, extend the heat treater’s capabilities by offering greater capacity.
