Purpose: The aim of this paper is to determine the influence of drawing speed of TRIP steel wires on their properties. Design/methodology/approach: The heat treatment of steel containing 0.09% carbon, 1.57% manganese and 0.9% silicon allows to obtain TRIP type structure. The wires were drawn with different drawing speed. After drawing mechanical properties of wires were determined by the tensile test. In this work also FEM modelling was done. Findings: The analysis of changes of mechanical properties after particular drawings stages was carried out. The increase of drawing speed cause the increase of strength properties and decreasing of plasticity properties of wires. It was shown that increase of drawing speed causes increase of: temperature, non-dilatation strain and internal stresses. Research limitations/implications: Continuation of the investigations with the use of scanning and transmission electron microscopy makes it possible to explain the changes properties of drawn wires by analyses of structure of drawn wires. Practical implications: TRIP steel wires, which have good mechanical properties and are dependent on drawing speed, can be used for production of connecting elements. Originality/value: For the first time there was shown the influence of drawing speed on properties of TRIP steel wires.
