Abstract Dualphase steel 09CuPCrNi was prepared through intercritical quenching process. The influence of dualphase treatment on corrosion resistant property of the steel was studied by electrochemical potentiodynamic test and salt spray test. The results indicate that the corrosion behavior of the dualphase weathering steel quenched at 780 ℃ and original weathering steel in 5%NaOH, 5%HCl, 5%H2SO4 and 3.5% NaCl aqueous solutions was identical, but the dualphase steel showed lower corrosion current. In salt spray test, the corrosion rates (mm/a) of dualphase steels were lower by 7.9%~22.2% (48 h) and 2.3%~130% (120 h).
