Servo Martemp is a premium-grade marquenching oil formulated to deliver superior performance, exceptional oxidation resistance, and long operational life in heat treatment processes. Designed using specially selected high-viscosity index base oils, this oil exhibits outstanding thermal stability, low volatility, and excellent fluidity, ensuring consistent quenching characteristics across multiple heat treatment cycles. It provides uniform cooling that prevents distortion and cracking, ensuring precise metallurgical results and extended component life. This oil is specifically recommended for marquenching and martempering applications, where achieving structural hardness without compromising dimensional accuracy is critical. Servo Martemp is widely used for quenching components such as gears, tools, dies, and bearings, delivering the ideal combination of hardness and toughness. It is highly suitable for heat-treating finished metal parts at bath temperatures ranging from 150°C to 200°C, where stable performance and minimal oxidation are required. The product’s excellent oxidation stability minimizes sludge formation and extends the oil’s working life, reducing the need for frequent replacement. Its consistent cooling characteristics help achieve uniform hardness across components, while its low evaporation rate ensures economical and safe operation even at elevated temperatures. With a flash point of 280°C (COC min) and a viscosity index of 90, Servo Martemp provides dependable performance under demanding industrial conditions. Servo Martemp offers a wide application range in steel manufacturing, automotive, and engineering industries, where controlled quenching and repeatable metallurgical results are essential. Its clean-running formulation ensures minimal residue formation, reduced maintenance requirements, and superior part finish quality. In summary, Servo Martemp stands as a reliable marquenching oil that combines thermal resilience, stable quenching performance, and oxidation resistance—making it the preferred choice for precision heat treatment operations that demand consistent quality, efficiency, and long service life.
