The corrosion of steel is a very important problem in steel structure and it is estimated that, in western industrialized countries, 2〜3% of gross national product is lost by corrosion.Therefore a lot of studies have been carried out on corrosion of various materials, and there are many data about corrosion.Data on corrosion,however,are rather biased and not classified systematically because of differant conditions. In this study,the authers paid our attention to the influence of corrosion on the strength and toughness of steel,and carried out the fatigue tests of corroded steel bars and plates. We also examined the effect of pre-strain on the corrosion of steel. We have come to the conclusion that the corrosion have considerable influence on the fatigue strength of steel and the pre-strain of steel would effect upon the corrosion.
