Sažetak
In this paper the effect of thermo-mechanical parameters on the mechanical behavior of a 9 % Cr-2 % W steel is investigated by hot rolling and heat treatment on pilot scale. Results show a strong effect of reheating temperature before rolling on the material hardness, due to an increase of hardenability following the austenite grain growth. A poor effect of the hot reduction and of the following tempering temperature is detected in the total investigated deformation range. A loss of impact energy is found coupled with the hardness increase. The tensile properties values are strongly depending upon the tempering temperature and an increase of tensile yield stress (Rp0,2) and ultimate stress (Rm) have been recorded in tensile test carried on at T = 550°C and T = 650°C.
