There is carried out a choice of efficient procedure for the microstructure detection of X2CrNiMoCuN25-6-3 duplex steel. The metallographic investigations of steel after different modes of its thermal treatment are fulfilled. There is chosen a mode, at which a structure with equal amount of ferrite and austenite is formed which allows forming an optimum complex of steel physical-mechanical properties.
