Features
1. High penetrating rate: Heat holds 8-10 hours, penetrating layer is 0.14-0.18mm, and bright white layer is 0.006-0.01mm.
2. High surface hardness: HV1,000-1,200
3. Big load capacity and low cost for heat-treatment: Low vacuum varying pressure technology fulfills good nitriding process. Fresh air reaches every corner of the inner furnace tank and provides perfect sealed environment, so that increases load capacity. 
4. Small surface friction coefficient.
5. Low brittleness.
6. Stable performance: With uniform and controllable atmosphere and temperature inside furnace, the vacuum varying pressure nitriding furnace ensures stable nitriding process and good nitriding effect.
7. Easy for operation
8. Wide adaptability, uniform seeping layer
