High-strength cast iron of grade VCh50 with globular graphite is studied after isothermal quenching in the bainitic and martensitic ranges. The mechanical properties of the iron and the hardness of its structural components are determined. The fine structure of the iron with bainitic and martensitic matrix is studied. The effect of the tempering temperature after the isothermal quenching on the hardness and structure of the iron is estimated.
