More recently a modified stainless steels have been used to produce various structural elements that work in complex operating conditions. 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 a 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. However, while sulfur improves machinability at the same time decreases the mechanical properties particularly toughness.
The aim of this work is to determine the influence of boron, zirconium and tellurium on the mechanical properties the mentioned steel. Change of mechanical properties, depending on the chemical composition of the steel is simulated with MATLAB program.
