Abstract
There is article discusses the process of modification of high-manganese steel, Hadfield, which will significantly increase the yield of the casting at the stage of melting and casting the steel. The steel modification performed integrated alloy FASC (ferroalumisilicocalcium) in an amount of 03 - 0,5% by weight of the metal. The integrated alloy unlike traditional methods of modification leads to globalizatsii and purification of steel from nonmetallic inclusions and for grinding grains of austenite, thereby greatly increases its mechanical properties.
