Abstract The descaling property of the oxide scale of high carbon steel wire were researched by the method of bending based on the electronic universal testing machine. Various characteristics of the samples of oxide scale were obtained through different cooling experiments. The descaling size of oxide scale samples with different thickness and microstructure was obtained by bending test. The results show that the descaling property of oxide scale was positively related to its thickness and negatively to the thickness ratio of FeO and Fe3O4. The descaling process of the oxide scale was affected by the stress condition and the descaling effect was better by compressive stress rather than tensile stress. Increasing oxidation temperature and oxidation time， reducing the cooling rate below 600 ℃ and increasing the amount of Fe3O4 can all improve the descaling property of the oxide scale.
