Abstract
The purpose of the present investigation is to determine the heat treatment parameters that ensure yield strength over 690 MPa in combination with toughness of at least 35 J/cm2 at temperature of –70°C in new economically alloyed cold-resistant steel. The effect of various quenching and tempering parameters on mechanical properties, structure of steel, and fracture mode of samples after impact tests at temperature of –70°C has been studied. The relationship between the properties, structure, and fracture mode of steel samples is shown. The heat treatment parameters of the investigated steel are determined.
