QUENCHING OIL
 

Description

This is blended with selected base oils to assist in rapid heat dissipation. The base oils must have the property of low volatility, high flash point and improved degree of oxidation stability so that the rate of heat dissipation is not impaired mainly on account of loss of lighter fractions.
 

Applications

  • This oil is employed for the heat treatment of metals as quenching media to acquire correct tempering of high Carbon Steel tools and other accessories.
     

Benefits

  • Good oxidation stability.
  • Good thermal stability.
