1.Material factor In induced quenching steel, manganese, chromium, and molybdenum content have the greatest effect on the depth fluctuation of the hardensed layer. If the cutting sensor quenching found that the heating layer is similar, the depth of the hardened layer is large, and the material ...

The gear induction of low-quenching steel is quenched is the former Soviet meritorious scientist invented. As early as the 1960s, it was applied to the automotive rear bridge gear, the tractor final drive gear, etc. In the 1970s, my country also developed 55Ti, 60Ti, 70Ti and other low-quenching ...

As early as 1948, the US General Motor Company applied to the medium frequency as a fundamental wave, but there was no inductive, but there was no available power supply and the appropriate power density, so this method has practical applications. Until 1993, Germany, Norwegian inventions were re...

The working conditions of the engine cylinder set are at a higher temperature, semi-drying state, and is strongly friction-by the piston ring, therefore, the surface of the cylinder line should have a high hardness; the cylinder line is also affected by the alternating load, so it is hard The sur...
