Isothermal graded quenching oil

With ideal cooling curve distribution，it can meet the requirements of sufficient surface hardness and hardening depth of the workpiece，and at the same time，it can well control the quenching deformation.

Product description

Parameters

1. With ideal cooling curve distribution，it can meet the requirements of sufficient surface hardness and hardening depth of the workpiece，and at the same time，it can well control the quenching deformation.

2. Less fuel consumption，easy to clean the workpiece

3. Excellent thermal oxidation stability，can maintain long-term stable brightness and cooling performance，long service life

4. Small oil fume，good environmental protection
