AB Subject of presented contribution is process formability parameters evaluation of both side coated TRIP and HSLA steels in basic state and after its annealing in order to Fe-Zn coating creation. The samples were annealed at 450, 500 and 550°C for 10 and 60 seconds in argon shielding gas. Obtained values are compared with each other in order to determine whether the influence of temperature and duration after annealing changed the original class inclusion on a scale to measure the quality of steel sheets for deep drawing according to the value of limit drawing ratio. Limit drawing ratio was used as a process formability criterion and were reached by modified Swift cupping test. HSLA steel H220PD and TRIP steel RAK40/70 were used as experimental materials.
