MAR-TEMP® 355 is a high performance accelerated hot quenching oil.
  • Suitable for use at temperatures of up to 375ºF (190ºC).
  • Designed for hot oil quenching applications where minimum distortion is required and a very high cooling rate is necessary to achieve the optimum hardness and physical properties.
  • Particularly recommended at temperatures of 250ºF (121ºC) to 350ºF (177ºC) in sealed quench furnaces for the control of distortion on critical high precision components such as bearing rings or automotive transmission parts in through hardened, carburized and carbonitrided steels.
