Servo Martemp 65 is a premium-grade marquenching oil designed to deliver superior performance in controlled heat treatment applications. It is specially formulated from highly refined, high-viscosity index base oils combined with carefully selected additives that provide exceptional oxidation and thermal stability. This ensures consistent quenching characteristics, longer service life, and uniform metallurgical properties in treated components. Developed for use in marquenching and martempering processes, Servo Martemp 65 provides structural hardness and dimensional stability to precision-engineered components such as gears, shafts, tools, dies, and bearings. Its excellent heat transfer efficiency enables uniform and distortion-free hardening, maintaining the desired microstructure across the entire surface of the metal. The oil exhibits outstanding resistance to oxidation and thermal degradation, reducing sludge and carbonaceous deposit formation, even under high-temperature operations. Servo Martemp 65 also features low volatility and excellent fluidity, ensuring consistent performance during prolonged service. With its controlled cooling rate, it minimizes quench cracking and distortion, resulting in superior surface finish and mechanical strength. Highly recommended for marquenching baths operating between 150°C and 200°C, this oil is ideally suited for industries engaged in automotive, tool manufacturing, engineering, and heat treatment applications. Its superior oxidation stability and minimal evaporative losses make it a reliable and cost-effective choice for modern quenching systems. By maintaining stable cooling characteristics and ensuring a uniform hardness profile, Servo Martemp 65 enhances productivity, reduces downtime, and prolongs bath life, making it a preferred choice for high-precision heat treatment operations.
