HP METAQUENCH 42 is a high-quality compounded quenching oil formulated from refined petroleum base stocks blended with superior-grade fatty oils to achieve enhanced wetting ability and efficient heat transfer characteristics. Designed for general-purpose quenching applications, this oil ensures uniform hardness, minimal distortion, and a smooth surface finish during heat-treatment processes. It meets the stringent requirements of IS:2664-1980 (Reaffirmed 1993) for compounded-type quenching oils, ensuring consistent quality and dependable performance in industrial operations. This oil exhibits faster quenching speeds than HP METAQUENCH 39 and HP METAQUENCH 40, making it ideal for situations where higher cooling rates are required to attain precise metallurgical results. The inherent thermal conductivity and oxidation stability of HP METAQUENCH 42 provide uniform cooling performance over prolonged use, reducing oxidation deposits and maintaining oil clarity.
