Abstract:Štore Steel je največji proizvajalec vzmetnega jekla v Evropi. Podjetje Štore Steel izdeluje več kot 1400 jekel različnih kvalitet z različnimi kemijskimi sestavami. Med njimi je 16MnCrS5, ki spada v skupino jekel za cementacijo. Le-ta so namenjena za strojno obdelavo različnih delov (npr. palic, plošč, trakov, odkovkov), pri katerih se zahteva kombinacija obrabne odpornosti, žilavosti ter trajno-nihajne trdnosti. Vse te lastnosti lahko povezujemo z natezno trdnostjo, ki je odvisna predvsem od kemične sestave in toplotne obdelave po valjanju. Prav tako je pomemben raztezek. V diplomskem delu je predstavljena metoda napovedovanja natezne trdnosti in raztezka s pomočjo linearne regresije. V napovednem modelu smo uporabili vsebnosti legirnih elementov v jeklu (C, Mn, S in Cr) ter načine toplotne obdelave. Glede na rezultate analize lahko povečamo natezno trdnost in izboljšamo raztezek.

Title:Response of mechanical properties on the steel 16MnCrS5 microstructure changes
Abstract:Štore Steel Ltd is one of the largest spring steel producers in Europe. Štore Steel makes more than 1400 steel grades, with different chemical composition. Among them is 16MnCrS5 steel, which is generally used for the fabrication of case-hardened machine parts for several applications (e.g. bars, rods, plates, strips, forgings) where combination of wear resistance, toughness and dynamic strength is essential. These qualities can be easily correlated with tensile strength, which depends on chemical composition and heat treatment after rolling. Also elongation should be taken into account. In the paper, modeling of tensile strength and elongation with linear regression modeling. The chemical composition (content of C, Mn, S and Cr) and heat treatment regime (GKZ or BG annealing) data were used for modeling. According to modeling results, higher tensile strength with improved elongation was achieved.
Keywords:16MnCrS5, tensile strength, modeling, elongation, linear regression
