Product Description
RQ 4000 is an isothermal mar-quenching oil with excellent thermal stability, rapid cooling performance, high flash point, and low viscosity.
Features and Benefits
1. High flash point ensures safety and suppresses smoke formation.
2. Low viscosity minimizes drag-out loss (oil agitation loss).
3. Excellent thermal-oxidative stability for long service life at high temperatures.
4. Delivers uniform hardness and bright, residue-free surface after quenching.
5. Free of harmful substances ensuring easy and safe disposal.
Applications
1. Suitable for mar-quenching processes in the automotive industry for castings, gears, springs, bearings, screws, etc.
2. Ideal for carburized or carbonitrided bearings, gears, and small to medium-sized parts in controlled atmosphere or continuous furnaces
3. Recommended for quenching materials such as alloy steels and carburizing steels within a temperature range of 120–160°C
