Abstract
The influence of temperature and time of heating for quenching, type of cooling medium, temperature and heating time during low tempering on the structure, phase composition, hardness, mechanical properties during tension and impact bending of sheet semi-finished products made of high-strength chromium-nickel-molybdenum-vanadium steel has been studied. As a result of the research, optimal parameters for the final heat treatment of workpieces from the steel under study have been determined for the manufacture of parts operating under conditions of intense shock and cyclic loading at temperatures up to minus 60°C.
