Special Features of Recrystallization of Rolled Sections from Austenitic Chromium-Nickel Steels Under Thermal Deformation Treatment

  • CORROSION-RESISTANT STEELS

Metal Science and Heat Treatment Aims and scope

Regular features of the effect of recrystallization of austenite under hot deformation on the formation of structure in thermal deformation treatment (with subsequent hold in the furnace and without it) of rolled sections from corrosion-resistant austenitic chromium-nickel steels 10Kh17N13M2T (EI-447) and 12Kh18N19MT are investigated. The kinetics of the austenite recrystallization is studied by metallography and measurement of the hardness of specimens and of the microhardness of recrystallized and not recrystallized grains. The volume of the recrystallized grains and their mean size are determined. The effect of the homogenizing modes in heating for quenching, and of accelerated and decelerated cooling after rolling in a 1050/950 rolling mill of the “Dneprospetsstal’” Company on the impact toughness of the steels is studied.
