EFFECT OF METALLURGIC PURITY OF THE 15CrMoV6-10-3 (15HGMV) STEEL ON TECHNOLOGICAL AND MECHANICAL PROPERTIES OF COLD-DEFORMED PRODUCTS
The subject of the article is the analysis of the impact of electro-slag remelting – ESR on the technological and mechanical properties of the 15HGMV steel. Uniaxial compression tests were carried out with the use of a Gleeble simulator. The hardness and microstructure of deformed samples were tested. The mechanical properties were measured in a static tensile test. Significantly larger non-metallic inclusions were found in the material without ESR, as compared to the material with ESR, which may be decisive in further processing of the material in the form of thin-walled tubes with the use of cold flow forming.
