Abstract

More recently 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 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. However, sulphur at the same time decreases the mechanical properties, 
particularly toughness. The addition of sulphur, which is the cheapest available additive for free 
machining, will impair not only the transverse strength and toughness but also the corrosion 
resistance.
The aim of this work is to determine the influence of tellurium on the machinability, corrosion 
resistance and mechanical properties of the mentioned steel.
