The effect of heat treatment on the fatigue processes developing in tool steel 6KhS loaded by a “soft” scheme of cantilever bending of flat specimens is studied. The fatigue limit and the cyclic endurance are determined. The frequency characteristics and the dynamics of the frequency stability in tests of steel specimens at a load close to the fatigue limit are presented. The fatigue resistance of the steel after low-temperature tempering is shown to be highly scattered. The steel exhibits the highest frequency stability after high-temperature tempering.
