Product Description:
RQ 4000 is an isothermal step quenching oil with excellent thermal stability, rapid cooling, high flash point and low viscosity.
Features and Benefits:
1. High flash point to ensure safety and reduce smoke.
2. Lower viscosity to reduce oil churning power loss.
3. Excellent thermal oxidation stability with long service life at high temperatures.
4. Brings brightness and uniform hardness to workpieces after quenching.
5. No harmful substances, easy disposal.
Applications:
1. Mainly suitable for step quenching process in the automotive industry, such as casting, gear, spring, bearing and screw in.
2. Suitable for carburizing or carbonitriding bearing, gear and other small-and-medium sized workpieces in the multipurpose controlled atmosphere furnace or in the continuous furnace.
3. Suitable for alloy steel, carburizing steel and other materials with working temperature range from 120℃ to 160℃.
