Sažetak
In this paper some interesting experimentally determined actualities referring to the 50CrMo4 steel are presented. In that way, the material mechanical properties are derived from uniaxial tensile tests at lowered and elevated temperatures. Engineering stress versus strain diagrams for both of mentioned temperatures, curves representing the effect of temperature on specimen elongation and short-time creep curves are given. Notch impact energy test was also carried out. Taking into consideration service life of final product of the mentioned steel widely used in engine and machine technology, all of the mentioned data may be relevant during design and manufacturing procedure.
