A method for measuring corrosion performance of materials belongs to the technical field of material corrosion. Test materials include carbon steel, alloy steel, stainless steel and other various materials or nonferrous alloy. Sample state comprises rolling control, rolling control cold control or heat processing. 5%-50% tensile strain preprocessing is conducted before an corrosion test, then mechanical polishing is conducted on a test piece, the test piece is placed in corrosion media after being weighed and is taken out after being placed for a certain time under the opening or closing condition, then the test piece is weighed, and weight change is compared. Corrosion environment temperature is the normal temperature, and the humidity is the relative saturation humidity. The corrosion media comprise gas and liquid, the gas is mixed gas composed of corrosive gas including SO2 and CO2 with certain density, and the liquid includes water solution composed of picric acid and sodium hydroxide and the like. The method has the advantages of being high in test speed, high in result accuracy and simple to operate and is suitable for being applied to quickly detection of corrosion performance of the carbon steel, the alloy steel, the stainless steel and other various materials or nonferrous alloy on a production site.
