Fast quenching oil
Fast quenching oil
This product is adjusted by the following method, the lubricating oil fraction is obtained by distillation of crude oil or cacuum distillation,dewaxing. solvent refining. clay and refined .adding refrigerant.antioxidant, metal deactivator.
The product has a cooling speed. oxidation stability, strong anti-rust effect. less fuel comsumption. long service life. The product is suitable for demanding high-speed quenching and tempering. carburizing and other parts and large cast parts large gear and quenching press quenching. The product is used at a temprature of 20-80℃。
