“…As well as selenium, it also promotes globularization and expansion of sulphide inclusions. Although tellurium is now recognized as a powerful sulphur modifier as well as a machinability additive when used in combination with lead and sulphur [2], it also has a downside because it causes problems with hot processing of austenitic stainless steels and has not been used for commercial purposes [3].…”

Stainless steel X8CrNiS18-9 (standard EN 10088-3: 2005) is the most commonly used austenitic stainless steel due to its good machinability. This steel has high mechanical and working properties thanks to complex alloying, primarily with the elements such as chromium and nickel. The content of sulfur present in the steel from 0.15 to 0.35% improves machinability. Microalloying with tellurium and zirconium (individually and in combination) in most cases leads to improved properties of this stainless steel, compared to melt without alloying additives, e.g. the melt microalloyed with tellurium and especially melt microalloyed with zirconium and tellurium has significantly better machinability compared to the melt without alloying elements. The addition of sulfur, which is the cheapest available additive for free machining, will impair not only the transverse strength and toughness but also the corrosion resistance. However, while sulfur improves machinability at the same time decreases the mechanical properties, particularly toughness. This work aims to test the machinability, corrosion resistance, and mechanical properties of the mentioned steel, as well as the chemical composition of non-metallic inclusions.

“…The research was carried out on an austenitic stainless steel labelled X8CrNiS18-9, as defined in standard EN 10088-3: 2005, which was produced at semi-industrial plants at the Institute "Kemal Kapetanović", University of Zenica, in order to determine the influence of zirconium and tellurium in austenitic stainless steel [1]. Grade X8CrNiS18-9 is the most readily machinable of all the austenitic grades of stainless steel.…”

“…Than the analysis of the content, size and distribution of non-metallic inclusions in non-etched state was carried out at the Institute of Zenica, Bosnia and Herzegovina. For each of the above samples, line and point analysis were done, and also mapping[1,8]. The detailed SEM/EDS analyses of modified nonmetallic inclusions were performed by scanning electron microscope (SEM) Jeol JSM 5610 with attached energy-dispersive x-ray spectroscopy (EDS) system.…”

Control of the formation of nonmetallic inclusions and their characterization is the foundation for improving the qualities of steel products, as well as designing new types of steel. In order to produce steel with improved machinability, such as austenitic stainless steel X8CrNiS18-9, is made modification of the chemical composition of nonmetallic inclusions. In this paper, Thermo-Calc phase calculation and SEM studies of the presence and type of inclusions in austenitic stainless steel with the addition of sulphur of the label X8CrNiS18-9 with and without addition of alloying elements Zr and Te, were carried out individually in order to investigate their influence on the shape and chemical composition of the inclusions.
