Abstract：With the help of thermo-mechanical simulation and numerical simulation, the application of HTP process in high strength steel (yield strength is no less than 600MPa) with the thickness less than 100mm was discussed, in which Nb, Mn, Cr and B were added and two Nb content(0.09% and 0.05%) steel were contrasted. The results show that by using HTP and temper process, non-recrystallization temperature of steel plate is increased, homogeneity and toughness at center of ultra-heavy plate is obviously increased. The microstructure is mainly lath-like bainite on surface and at quarter, and grain bainite and black pearl-like at center of the thickness by different cooling rate.
