FUCHS THERMISOL QH 40 is a high-performance, thermally stable hardening and quenching oil formulated with highly refined mineral base stocks. Engineered for precision heat-treatment processes, it features a high flash point combined with controlled viscosity to deliver rapid, uniform cooling while keeping evaporation and drag-out losses to a minimum. It is designed for hardening both unalloyed and alloyed case-hardening steels, quenched and tempered steels, and tool steels in open and closed quenching systems.
