Premium quality quenching oil designed to provide controlled cooking of steel which is important in steel hardening. When quenching is started, Chevron Quenching Oil 70 provides a high initial cooling rate inducing maximum hardness, yet once the critical transformation temperature is passed, the ideal fluid cooling rate decreases to eliminate the possibility of stresses and metal distortion.
This highly stable oil resists the oxidizing effects of quenching and is less sensitive to the effects of agitation. It is highly heat resistant. No additive replacement is required and, in normal service, the product retains the original voscosity indefinitely.
