“…As there was no deterioration of tar epoxy resin coating observed after 10‐day exposure to artificial sea water, it can be concluded that enough improvement of the corrosion fatigue strength is expected as long as cracks do not initiate in the tar epoxy resin coating. The fracture surface morphology of the ultrasonically tested corrosion fatigue specimens was basically the same as that of conventional corrosion fatigue tested specimens 19 …”

In this paper, long‐term corrosion fatigue behaviour of structural materials such as 12Cr stainless steel and Ti−6Al−4V alloy for steam turbine moving blade and high‐strength steels for ship and offshore structures up to the ultrasonic frequencies is reviewed mainly on the basis of the author's experimental results. The emphasis is focused upon the corrosion fatigue behaviour of 12Cr stainless steel in NaCl and NaOH aqueous solutions. It is shown that the corrosion fatigue strength of 12Cr stainless steel is strongly dependent on NaCl content in aqueous solution. It is also exemplified that the ultrasonic corrosion fatigue strength of 12Cr stainless steel decreases remarkably if an aggressive environment like 40% NaOH aqueous solution should be formed at the crack bottom even in a dilute NaOH aqueous solution.

“…(2001), concluded that, corrosion fatigue life of welded joints can be improved greatly, by coating with tar epoxy resins [26]. Ebara R (2001), demonstrated that, corrosion fatigue strength of KA32 (TMCP) steel can be improved by tar epoxy resin coating and an acceleration of corrosion fatigue crack propagation rate, for KA36 (TMCP) and KAS steel was observed in the higher stress intensity factor range, under sour crude oil environment [27].…”

This paper describes corrosion fatigue properties of KA40 which is high tensile steel for a ship hull approved by Class NK. The structure of a ship hull is in a severe corrosive environment and subjected to cyclic loads due to waves. It is important to grasp the corrosion fatigue properties of materials for the structure of a ship hull. However, there are few reports of corrosion fatigue test results for hull structural materials. Therefore, further data accumulation is required to understand the corrosion fatigue properties of hull structure composed of materials with various mechanical properties. In this study, fatigue tests and fatigue crack propagation tests by using specimens for KA40 were carried out both in air and in synthetic seawater. Furthermore, in comparison of the results of KA40 with the results of KA32, the relationship between the difference in mechanical properties and the corrosion fatigue properties of each material is discussed.
