Heat treatment process of 42CrMo steel forging. Heat Treatment Properties of 42CrMo Steel for Bearing Ring The heat treatment properties of 42CrMo steel for bearing ring of varisized shield tunneling machine were investigated by optical microscope (OM), scanning electron microscope (SEM), transmission electron microscope (TEM), and impact tests. The addition of 0.03 wt% C into 42CrMo steel can increase the hardness.

Normalizing specificationNormalizing temperature is 850~900 °C, and the air is cooled.42CrMo4 datasheet,42CrMo4 chemical,42CrMo4 heat treatmentThe concentration of alloy element of this kind of steel is quite high, mainly are corrosion resistant steel, heat resistant steel, wear resistant steel, and other special steels of physical and chemical properties. Alloy structural steel has preferable mechanical property than that of carbon structural steel, high performance of heat treatment especially.
Apr 24, 2020· EP treatment was applied to 42CrMo steel. The microstructures of 42CrMo samples after EP quenching and tempering were studied. Compared with conventional heat treatment, EP treatment demonstrates dramatic PAGs and carbides size refinement potencies. The strength of 42CrMo steel after EP treatment was improved.QPQ Salt Bath Nitriding Treatment of 42CrMo ProductsQPQ Salt Bath Nitriding Treatment of 42CrMo Products QPQ technology can complete heat treatment and anti corrosion treatment at one time, with low temperature and short time. It can also improve the surface hardness, wear resistance and anti corrosion of parts, reduce friction coefficient, small deformation and no pollution. CROMAX® 42CrMo4 (4140)Other heat treatment conditions can be supplied by special arrangement. CHROME LAYERThe thickness of the chrome layer is minimum 20 m.
