HP METAQUENCH 44 is a superior-grade, additive-type quenching oil formulated from refined mineral base oils and fortified with advanced dispersant additives to ensure excellent thermal stability, minimal quench distortion, and enhanced surface hardness. It conforms to IS:2664-1980 (Additive Type) specifications and is specifically designed for applications where cleanliness, higher surface hardness, and precise metallurgical results are critical. This oil combines exceptional dispersant and wetting properties, which help maintain clean metal surfaces by preventing the accumulation of dirt, scale, and oxidation residues during the quenching process. Its carefully balanced formulation allows for significantly faster cooling rates compared to conventional quenching oils, resulting in improved hardness penetration and a superior surface finish. The dispersant additives also contribute to minimizing sludge formation and metal fouling, ensuring consistent performance and extended oil life.
