Abstract
On the basis of constant amplitude fatigue tests with f = 0.1 s^−1^ of butt welded specimen of a high strength structural steel St E 460 the effect of natural seawater as well as an additional biofouling coating on the endurance was evaluated in comparison to the effect of synthetic seawater. The results demonstrated that the number of cycles to failure in natural seawater – including biofouling – was significant smaller than in abiotic synthetic seawater (ASTM). This points out that for absolute statements based on an absolute outcome the biological effects of natural seawater must be taken into account.
