This paper is devoted to influence of the size and number of graphite inclusions in high-strength cast iron on pre-shrinkage expansion and, as a result, on linear shrinkage and dimensional accuracy of castings. It was established that influencing the number and size of graphite inclusions it is possible to increase the dimensional accuracy of high-strength cast iron castings by two accuracy classes and significantly reduce mechanical processing allowances of cast iron in order to save metal.
