Целью изобретени   вл етс  повышение технологических свойств .стали However, the well-known steel is characterized by low technological properties and the inability to perceive directly quenching from the cementing tetrapure. The low technological properties of the known steel are poor machinability at low temperatures, low surface hardness and low ductility values. The aim of the invention is to improve the technological properties of steel.
