HEAT TREATMENT
Heat C45E Fabrication to 850 to 1200°C, forged C45E by Hammer. At 820-855°C, Quenching in air or oil. before quench, ensure heat thoroughly. Heat to 550-660°C for Tempering.
FORGING
The forging temperature of C45E+N steel is usually between 900-1100°C, depending on the desired shape and properties. After forging, the steel should be cooled slowly to reduce thermal stress and deformation.
