C45E Steel Round Bar Coil Sheet Plate Heat Treatment

C45E / 1.1191 Steel Normalizing
850℃-920℃, slowly cooling in air.

DIN C45E Steel Annealing
800-850°C, fully soaked. Then cool slowly in the oven.

Hardening of Carbon Steel C45E Material
Quenched in air or oil at 820-860°C. Before quenching, make sure to heat thoroughly.

C45E Steel Tempering
Temper by heating to 550-660°C. Cool in still air, according to different hardness and requirements, determine the temperature.

Stress Relief
550°C – 660°C, cooled in still air.

Forging of C45E Steel
Heat the C45E fabrication to 850 to 1200°C to forge the C45E with a hammer.
