THE INFLUENCE OF MICROALLOYING ELEMENTS ON CUTTING FORCE AND ROUGHNESS OF AUSTENITE STAINLESS STEEL

More recently a modified stainless steels have been used to produce various structural elements that work in complex operating conditions. Stainless steel X8CrNiS18-9 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 sulphur present in the steel from 0.15 to 0.35% improves machinability. The aim of this work is to determine the influence of microalloying with boron, zirconium and tellurium on the cutting force and roughness the mentioned steel.
