Preheat the steel carefully, then raise temperature to 1100°C for forging. Do not forge below 850°C. After forging cool slowly, preferably in a furnace.

Heat slowly to 680-710°C, soak well. Cool slowly in the furnace.

Heat the component slowly to 820-860°C and allow it to be heated through. Quench in oil or water.

Temper immediately after quenching whilst tools are still hand warm. Re-heat the C45  to the tempering temperature then soak for one hour per 25 millimetre of total thickness (2 hours minimum) Cool in air. For most applications temper between 550-660°C.

We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding C45 steel.

Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each C45 steel component.
