Effect of strain rates in dynamic plastometer tests on yield stress of steel wires with boron

Effect of strain rates in dynamic plastometer tests on yield stress of steel wires with boron

Screws for the automobile industry were manufactured from wires of steel 23 MnB4 with carbon content 0.1-0.15 percent. In many cases, these screws exhibited surface defects (pitting). A boron-modified steel grade has been proposed to eliminate surface defects and improve wire plasticity. In this work, a physical model of steel wiredrawing has been developed based on plastometer dynamic tests of wires with 12.5 and 11 mm diameter and strain rates in the 1-63 s-1 range. The model was verified by using bench-scale wiredrawing. This work showed that the addition of boron increased yield stress of the steel and a degree of deformation.
