The study describes the effect of heat treatment on the microstructure of cast high-alloyed 20%Cr-21%Ni-5%Si steel. It has been found that the microstructure of the tested material in the initial state consists of an austenitic matrix and precipitates rich in Si, Cr, Ni and Mn, characterized by different morphology and distributed mainly along the grain boundaries. The conducted heat treatment (after solutioning at: 1060, 1100 and 1200ºC) has changed both morphology and chemical composition of the precipitates. Significant reduction in the Si and Ni content and slight increase in the Cr content, especially after solutioning at 1200°C, combined with a simultaneous decrease in the hardness of the precipitates was evidenced.
