Influence of a Zinc Coating on the Mechanical Properties of a Low-Carbon Steel Microalloyed with Niobium
Tóm tắt
The mechanical properties of a 08GBYu sheet steel ((wt %) 0.08 C, 1.0 Mn, 0.04 Nb, 0.04 Al) with a zinc coating and after its electrolytic removal are studied. The mechanical properties of the galvanized steel are shown to change insignificantly in the strain rate range from 8.3 × 10–5 to 25 × 10–3 s–1. The fatigue limit under repeated tension is 400 MPa. The strength properties and the fatigue limit of the steel base increase by 11–13% after electrolytic removal of the coating. The load on an indenter is determined to analyze the hardness of both the coating and the steel with the coating.
