The invention relates to a corrosion resistant hinge, and belongs to the technical field of alloy material processing. The corrosion resistant hinge is made of alloy steel. The alloy steel comprises, by mass, 0.10%-0.15% of C, 1.4%-1.6% of Cr, 0.14%-0.20% of Si, 0.8%-1.15% of Mn, 0.03%-0.05% of Al, 0.008%-0.015% of N, 0.12%-0.22% of Ti, 0.005%-0.022% of S, 0.08%-0.15% of V, 0-0.015% of P, and the balance Fe and inevitable impurities. The corrosion resistant hinge is formed through the steps of raw material steelmaking, subzero treatment, electroplating, passivation and sealing treatment processing. The corrosion resistant hinge is good in corrosion resistance and mechanical property.
