Quench Oils are high-quality oils developed for heat treatment of ferrous metals in a wide variety of quenching operations. They are formulated to provide deep and uniform hardening with minimum distortion and cracking for a smooth surface finish.

Features & Benefits
- Controlled cooling rate to minimize cracking and distortion
- Good surface finish
- Excellent oxidation resistance and thermal stability
- High flash point for fire safetyNote: Agitation, filtration and periodic product sweetening are essential to successful quenching operations. The quench tanks must be periodically cleaned and the quench oil filtered to remove scale, metal shavings and contaminants. A 50-micron double-bag filter is recommended for proper maintenance. The quench oil must be continuously agitated to provide uniform surface microstructure. Condition monitoring by oil analysis is essential in maintaining optimum performance and the desired quenching qualities of these oils.
Applications
- Conventional and fast quenching of ferrous metals, such as carbon steel, gray iron and high-alloy steelCaution: Quench Oils must not be mixed with competitive quench oils, unless tested for compatibility. They are not recommended for marquenching or martempering operations, where oil temperatures can reach 150°C to 232°C (302°F to 450°F).
