HP METAQUENCH 43 is a high-performance additive-type quenching oil formulated from refined mineral base stocks and fortified with advanced dispersant additives to provide superior heat-transfer efficiency and minimal quench distortion. It conforms to IS:2664-1980 Additive Type specifications and is specially designed for applications where the prevention of metal soiling during quenching is essential. This oil ensures uniform metallurgical results, controlled cooling rates, and a clean metal surface after quenching. The formulation contains carefully selected dispersants that actively inhibit the accumulation of dirt, carbon, and metallic oxides on the surface of components, maintaining cleaner baths and preventing uneven hardness or surface defects. Its excellent thermal conductivity enables rapid and uniform heat dissipation, ensuring consistent hardness and reduced internal stresses. With high oxidation stability and low volatility, HP METAQUENCH 43 offers extended service life, reduced oil degradation, and minimal evaporation losses, making it an ideal choice for continuous industrial heat-treatment operations.
