DETAIL CASTING USING SECONDARY METALS IN FOUNDRY ACCORDING TO GOOST MARKINGS

This article studies the scientific and technological aspects of casting parts in accordance with GOST standards using secondary metals in foundry. During the study, the influence of the chemical composition, alloying elements and heat treatment of secondary metals on the quality and mechanical properties of the part was analyzed. In experimental work, samples made from steel and iron alloys were tested for compliance with GOST standards. The results showed that the use of secondary metals reduces production costs and extends the service life of the part. At the same time, quality and reliability can be ensured through material optimization and control of casting technology
