Heat treatment oil, also known as quenching oil or heat transfer oil, is a specialized type of industrial fluid used in the heat treatment of metals.
Heat treatment is a process used to alter the physical and mechanical properties of metallic components, such as steel, by subjecting them to controlled heating and cooling under specific conditions.
Quenching, which is a critical stage of the heat treatment process, involves rapid cooling of the heated metal to achieve the desired material characteristics, such as hardness, strength, and dimensional stability.
