Performance characteristics and application range of heat treated oil:
1, ordinary quenching oil: strong cooling performance, good oxidation stability, suitable for salt bath furnace or protective atmosphere of bearing steel, tool steel, alloy steel and carburized steel and other parts of the quenching.The best temperature 50-80 ℃.
2, fast quenching oil: cooling speed, good oxidation stability, bright medium, suitable for high speed quenching quenching quenching quenching and other parts and large forging pieces, large gear and quenching press.Use temperature of 20-80 ℃.
3, fast bright quenching oil: fast cooling speed, good oxidation stability, bright, suitable for bearing steel, die steel and other structural steel quenching in the protective atmosphere.Use temperature of 20-80 ℃.
4, overspeed quenching oil: faster cooling speed, good oxidation stability, suitable for automobile, bearing, mining machinery, metallurgical machinery and die industry large parts of the heating quenching, carburizing or carbonitriding quenching, also suitable for medium carbon steel and other types of alloy steel quenching.Using 20 to 60 ℃ temperature.
5, vacuum quenching oil: saturated steam pressure, good cooling performance, good brightness, suitable for bearing steel, mold steel, medium and large aerospace structure steel and other materials of vacuum quenching, the first time should be in the vacuum oil air.Use temperature of 20-80 ℃.
6, isothermal graded quenching oil: good cooling performance, small deformation parts, suitable for bearing steel, carburized steel bearing inner and outer circle, precision parts, automobile gear, half shaft and other workpieces and easily deformed parts quenching.Using the temperature 120 ℃, 1 no. 2 to 150 ℃.
7, back to heat the oil, high viscosity, flash point, volatile small, thermal oxidation stability, is suitable for workpiece tempering after quenching, 1 150 ℃ temperature, no. 2 use temperature 200 ℃.ISO/DIS 6743/14 classification of lubricants, industrial lubricants and related products (group L) - part 14: group U (heat treatment).In China, the classification standard of heat treatment oil sh0564-93 is put forward according to JIS-K2242-80 standard.
