Quenching Oil

Quenching oil is a mineral oil-based liquid medium with strong cooling performance and excellent oxidation stability, suitable for small parts that require rapid cooling and are sensitive to deformation.

  • KR498

    Quenching deformation is one of the three primary challenges in heat treatment quality control. KR498 Isothermal Graded Quenching Oil effectively reduces quenching deformation in thin-walled, complex-shaped workpieces such as automotive gears, motorcycle gears, clutch plates, and bearing rings. This results in improved product precision, reduced machining allowance, and significantly lower production costs.

  • KR098

    Insufficient hardness in high-chromium steel balls is a common issue with air quenching. Increasing alloy content raises production costs and often has limited effectiveness. In response, many wear-resistant manufacturers are considering quenching oil instead. KR098 Quenching Oil, specifically tailored for the steel ball industry, significantly enhances the quenching hardness of high-chromium steel balls. It addresses issues such as inadequate hardness and poor impact toughness associated with air quenching, while also reducing production costs and enhancing market competitiveness for enterprises.
