The master thesis ''Simulation of hot rolling of AISI 321H, 316L and 304L quarto stainless steel plates'' was carried out to determine the formability of the steels in question for the calibration of the microstructure modelling software RSProSim and for the industrial validation of the results obtained with RSProSim. The formability was determined by pressure tests on the Gleeble 1500D thermomechanical metallurgical simulator. In addition, grain growth tests were performed on the Gleeble 1500D and in the Bosio EUP-100/1250C chamber furnace. The industrial validation was performed by grain analysis of hot rolled slabs from SIJ Acroni Ltd. The stainless steels AISI 321H, 316L and 304L are austenitic stainless steels. The pressure tests were carried out at temperatures of 1250, 1200, 1150, 1100, 1050, 1000 and 950 °C and strain rates of 10, 1 and 0.1 s-1. Grain growth tests were carried out for all steels at 1150 °C for up to 600 s. The annealing temperatures in the chamber furnace were 1120 °C for AISI 321H, 1070 °C for AISI 316L and 1050 °C for AISI 304L. RSProSim describes the evolution of the microstructure during the hot rolling process. Industrial validation was performed by comparing the crystal grain size distribution during hot rolling of the plate with the calculated results from RSProSim. The simulation was carried out at the same parameters at which the rolling was carried out.
