Houghton Mar-Temp 340 - High performance accelerated hot quenching oil - 52340
Mar-Temp 340 is a high performance accelerated hot quenching oil suitable for use at temperatures of up to 200ºC. It is based upon solvent-refined mineral oils and contains a specially formulated additive package which provides accelerated quenching characteristics and excellent oxidation resistance and thermal stability. Mar-Temp 340 has a high flash point and will provide long life under arduous operating conditions.
Mar-Temp 340 is 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. It finds particular application in sealed quench furnaces at temperatures up to 200ºC, under a protective atmosphere, for the control of distortion on critical high precision components such as bearing rings or automotive transmission parts in through hardened, carburised and carbo-nitrided steels. It can also be used in open tanks at temperatures in excess of 100ºC for the quenching of gears and shafts.
