Purpose: Purpose of this article is to extend a complex evaluation of fatigue properties of micro-alloyed 23MnB4 steel in initial state and after heat treatment. Design/methodology/approach: Testing of micro-alloyed 23MnB4 steel was based on fatigue test completed by metallographic and fracture analyses. The methods of the light microscopy and SEM were used. Findings: Objective of this work consisted in determination of fatigue characteristics of micro-alloyed 23MnB4 steel, including fracture analyze. Results of fatigue testing at various stress levels for the samples in initial state and after the heat treatment have confirmed that obtained values of cycles to rupture were at least 585 000 cycles. Change of fatigue properties in dependence on heat treatment of the used steel. Research limitations/implications: The experiment was limited by occurrence a void in cast alloys. Practical implications: The results may be utilized for application of the investigated material in process of manufacturing. Originality/value: These results contribute to explanation of fracture mechanism of micro-alloyed 23MnB4 steel.
