The present invention relates to an anticorrosive agent for cavity preservation, and to the use thereof. The anticorrosive agent has a base composition of 40 to 50 wt. % base fluid, 3 to 10 wt. % alkyd resin, 10 to 20 wt. % sulfonate and/or salicylate component, 15 to 25 wt.˜% filler, 0.003 to 0.007 wt. % siccative catalyst, based in each case on the total mass of the anticorrosive agent. In addition to the base mixture, the anticorrosive agent includes 1 to 5 wt. % phyllosilicate and/or 1 to 8 wt.˜% ester wax and/or paraffin wax, based in each case on the total mass of the anticorrosive agent, for adjusting the rheological properties of the anticorrosive agent. The anticorrosive agent, however, does not include any aminic corrosion protection or binder components, or any anti-skinning agent.

A surface-treated steel material having cut edge corrosion resistance that is equal to or more than that of a chromate treatment without use of hexavalent chromium. The surface-treated steel material includes a coating film formed on a surface of a steel material through a plating layer that is obtained by immersing the steel material in a galvalume bath containing Mg. The coating film is formed using a coating composition containing a coating film-forming resin, a cross-linking agent, a predetermined vanadium compound, and trimagnesium phosphate; the vanadium compound is a compound satisfying a predetermined electrical conductivity; the content of the vanadium compound is restricted to a predetermined amount; the vanadium compound satisfies a predetermined pH; and the content of the trimagnesium phosphate is a predetermined amount.
