The book systematizes and analyzes the results of the latest (by that time) scientific research in the field of production and properties of cast iron. The authors (specify if known) rely on both domestic and foreign sources, describe the physico-chemical features of cast iron, the effect of alloying additives, temperature regimes and cooling methods on its structure and mechanical properties. Special attention is paid to the practical use of cast iron in mechanical engineering, construction and other industries. Given the context of the 1930s, the publication also gives an idea of the level of development of scientific thought in the USSR and the desire for industrialization. Value: Historical: A rare publication reflecting the scientific picture of the pre-war period.
