This is a water-soluble quenching medium of PAG polymer, which is characterized by being soluble in water and formulated with various quenching media with different cooling characteristics. It has the characteristics of ideal quenching medium and the workpiece is above 650 °C. The cooling is slower to reduce the risk of deformation and cracking; in the austenitic unstable zone, 650~400 °C has a sufficient cooling rate to prevent the transformation of austenite to pearlite; when it is below 300 °C, its cooling rate It is slower, which prevents great internal stress during martensitic transformation and helps to reduce deformation or even cracking of the workpiece.
Forged steel crankshaft
There are many kinds of crankshafts produced by our company. The main materials are: 45 steel, 40Cr, 42CrMo, 48MnV. The processing route of forged steel crankshaft is: forging→tempering→roughing→de-stressing tempering→semi-finishing→surface quenching→tempering→blasting→finishing.
