PROBLEM TO BE SOLVED: To provide a life prediction method for steel materials, capable of precisely predicting amounts of long-term corrosion of various steel materials from short-term data, and to provide a design method for the steel materials and their structure. SOLUTION: The life prediction method for the steel material uses a corrosion amount prediction relation Y=AX<SP>B</SP>for the steel material of the structure, (wherein Y: amount of corrosion, X: years, and A, B: factor and power number each depending on materials and environments). The above value A is determined from an exposure test at an installation place of the structure, and the above value B is derived as a function of the value A, and then the amount of corrosion Y of the steel material is calculated from the value A and the value B.
