HP METAQUENCH 85 is a premium-grade marquenching oil specially formulated for controlled quenching operations that demand uniform hardness, reduced distortion, and excellent metallurgical stability. It conforms to IS:4543-1977 specifications and is designed for use in temperature-controlled quench baths operating between 150°C and 220°C, ideal for marquenching or austempering processes where gradual cooling is essential. This high-quality quenching oil is developed from refined base oils with superior oxidation and thermal stability, ensuring consistent performance during prolonged use at elevated temperatures. HP METAQUENCH 85 provides low and predictable quenching rates, which help minimize internal stresses and distortion, making it highly suitable for the mass production of precision-engineered components such as bearing races, gears, and transmission parts. Its excellent heat transfer characteristics ensure uniform temperature distribution across the quench bath, contributing to consistent hardness and microstructure throughout the treated components.
