摘要：

Austenitic stainless steel is a useful material for various industrial facilities such as the nuclear and steam power plant and the heavy chemical industry due to its good corrosion resistance and mechanical properties. However, it has also a large problem that austenitic stainless steel is sensitized in the welding process and its corrosion resistance and mechanical properties decreases by sensitization. Thus, in this paper, corrosion fatigue characteristics of artificially sensitized austenitic STS304 were investigated through corrosion fatigue test. From the results, corrosion fatigue strength of sensitized STS304 was remarkably reduced compare to non-sensitized ones. And it is expected that corrosion fatigue life of TMCP steel can be nondestructively predicted using the DCPD method.
