Bright quenching oil
Bright quenching oil
This product is prepared by these methods,such as crude oil is often vacuum distillation of the resulting lubrication oil fraction, dewaxing, solvent refining, clay added refined adding refrigerant, brightener and antioxidant. It has stability high finish. Quenching has a certain cooling capacity. Workpiece is oxidized after the fire has a clean mirror, long life and other characteristics.
The product is suitable for steel and instrumentation parts,such as small and medium cross-section bearing steel, tool and die steel.the amount of cutting tools in the protection of the atmosphere in the bright quenching.
