PURPOSE: A surface processing method of a steel material with a superior corrosion resistance is provided to replace stainless steel by forming a chromate layer and a nitride layer into multiple layers. CONSTITUTION: A surface processing method of a steel material with a superior corrosion resistance comprises the following steps: nitride processing the steel material in a furnace after washing(130); air-cooling the steel material by exposing the steel material outside(150); alkaline cleaning the steel material after oxygen-nitrification(210); separating an oxide layer formed during air-cooling(220); plating the steel material with zinc trivalence(300); and trivalence post-processing the steel material(400).
