【 摘 要 】

This contribution is based on an experimental programme which deals with the issue of blade steel T552 corrosion fatigue damage. The specimens were taken from a reference material delivered for blade production and tested in a corrosion cell under pre-stress of 300 MPa. A chloride solution of 35 ppm was chosen as the environment at a temperature of 80 C. Such an environment can be considered as the limit state that should not occur during the operating regime. The results are summarized and compared with experiments conducted at another workplace.
