Product Introduction:
Hardness is the high chromium steel ball's main problem after air cooling, and the increase of alloy content not only increases the production cost, but also the effect is not obvious. Therefore, many wearable steel ball plants tend to use quenching oil instead. KERUN®KR098 quenching oil is a customized product for the steel ball industry which can greatly improve the hardness of the steel ball and solve the problem of poor tenacity due to air cooling, meanwhile it greatly saves the production cost and improve the customer's competitiveness.
Product Features:
1.High flash point and high ignition point, safe to use
2.Martensitic isothermal quenching can be achieved to improve the product's overall mechanical properties
3.Low viscosity and low consumption
4.The surface of the workpiece is easy to clean after quenching
5.Good thermal oxidation stability and long service life
