● High-temperature cooling phase – Provides fast and uniform cooling;
Convection cooling phase – Offers slow and consistent cooling.
This dual-phase behavior ensures complete hardening of thick-section workpieces while minimizing distortion during quenching.
● Specially refined base oil with advanced additive technology – Ensures stable performance and long service life. Tests confirm that the cooling characteristics remain virtually unchanged even after prolonged use.
● High flash point and moderate viscosity – Results in low oil consumption under typical operating conditions, helping reduce operational costs.
● Low vapor pressure and low volatility – Ideal for protective atmosphere and carburizing quenching processes without affecting furnace atmosphere; also suitable for vacuum quenching.
