Product Introduction:
During many years of service in gearing industry, Kerun made deep studies in the problems of deformation during heat treatment of gearing. On this basis, the KR468C Gearing-specific quenching oil is developed, which is suitable for the quenching of gears for cars, mini cars, light and heavy vehicles, motorcycle gears and engineering machinery gears, effectively reduce the change of the shape and direction of gears and flatness during the cooling of the gears.
Product Features:
1.It is "tailored" according to the specific requirements of the gear, short vapor film stage, fast cooling at high temperature, and relatively slow cooling at low temperature
2.Entitle the gearing race with high and uniform surface hardness and enough hardening depth as well as control the deformation of the gears
3.Good thermal oxidation stability which keeps long-term stable cooling characteristics and long service life
4.Good brightness, easy to clean and shot blast
