Description	The formability of cold formed steel is conventionally improved by soft annealing which ensure spheroidization of carbides in final microstructure. Soft annealing is however a long and energy consuming process and therefore this article deals with the attempt to replace it by thermo-mechanical processing which combined hot deformation applied around A1 temperature with controlled heat treatment. Several strategies either with two deformation steps or with intensive incremental deformation were proposed with deformation temperatures of 700°C and 740°C and various subsequent holds at deformation temperature. The best results were obtained by the strategy with two deformation steps at 740°C (total ?=2.1) followed by 300s hold, which resulted in carbide spheroidization.
