METHOD AND APPARATUS FOR PREDICTING AMOUNT OF CORROSION WEAR LOSS IN WEAR-RESISTANT STEEL, METHOD FOR SELECTING STEEL TYPE APPLIED TO STEEL STRUCTURE, STEEL MATERIAL APPLIED TO STEEL STRUCTURE, AND BUSINESS METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To make the selling method of weather resistant steel efficient by providing a method for predicting corrosion wear loss in weather resistant steel, even if there are no actual measurement values for the amount of sulfuric acid oxide and the amount of flying salt content.;SOLUTION: The method for predicting the amount of corrosion in weather resistant steel is used to estimate information including weather observation data, in which weather resistant steel is exposed only from map information and construction conditions, the amount of flying salt content, and the amount of sulfuric acid oxide, and calculating the amount of corrosion wear loss, based on it in the method for predicting the amount of corrosion in unpainted or surface-treated weather resistant steel. The method for selecting a steel material, using the same and a surface treatment method, and the business method of weather resistant steel using the same are provided for calculating the corrosion wear amount extending to 100 years of design providing period.;COPYRIGHT: (C)2005,JPO&NCIPI
