Contribution deals with process formability evaluation of TRIP and HSLA steels, that were compared to typical deep drawing quality steel DC06. Process formability evaluation was performed by cupping test. Limit drawing ratio was used as a process formability criterion and drawing forces were measured during cupping test. There was used experimental-mathematic method for limit drawing ratio identification. HSLA steel H220PD with thickness 0,80 mm, TRIP steel RAK40/70 with thickness 0,75 mm and drawing quality steel DC06 with thickness 0,85 mm were used as experimental materials.
