Heat Treatment & Quench Oils
Idemitsu Quench Oils are highly refined oils that are thermally stable across large temperature ranges. With proper maintenance and additions of neat oil, there’s no need for tank-side additives such as oxidation inhibitors, quench speed and viscosity improvers.
Ideal for the heat treatment of carbon and alloy steel by flame, induction, and induction heating, as well as in batch and continuous furnace operations, Idemitsu Quench Oils are perfect for items such as large and small gears, shafts, transmission gears, camshafts, and pieces involving complex geometry and metallurgy, including bolts, bearings, and carbon steel parts.
Heat Treatment & Quench Oils
Idemitsu Water-Soluble Quench Polymers feature superior safety and environmental characteristics. Designed for both high and low hardened steel applications, quenching characteristics can be controlled for water and normal cold quenching oil by simply adjusting the concentration of the solution.

Idemitsu Lubricants Analysis System (I-LAS)
To assure optimal quench process control, it’s necessary to monitor quality variations throughout the life of an oil to minimize the formation of undesirable thermal and transformational gradients (sludge and varnish) that can lead to increased distortion and cracking. This is accomplished by establishing uncompromising quench bath maintenance procedures supported by the Idemitsu Lubricants Analysis System (I-LAS).
Idemitsu’s state-of-the-art lab offers superior testing services that support all your quench, lubrication, and coolant test needs. Trained engineers help determine which tests best fit your goals, helping you increase efficiency and save on quench costs. Idemitsu’s convenient, data-driven analysis system helps you manage and maintain optimal fluid health.
