Purpose: Influence of vanadium microaddition on structure and mechanical properties of the constructional spring steel was investigated. Design/methodology/approach: Metallography, transmission electron microscope, tensile test, hardness measurements have been used. Findings: Microaddition of V introduced to the steel allows to obtain the fine-grained structure, and gives elastic elements obtaining: apparent elastic limit Rp0.05 over 1800 MPa proof stress Rp0.2 over 1900 MPa and ultimate tensile strength over 1960 MPa after tempering at 450 degrees centigrade temperature. Research limitations/implications: TEM investigations on structure of the elastic elements after heat treatment were predicted. Practical implications: The carried out investigations showed a full suitability of the steel for production of springs and suspension springs with high strength properties, operating under conditions of high elastic strains. Originality/value: Conditions of heat treatment of elastic elements with the high strength properties were presented.
