摘要
The results of a set of experimental tests of Q420 steel samples with quality level Q420B are presented. The chemical composition of steel and its mechanical characteristics, indicated in the certificate for products and determined experimentally, were compared with the standard values in the certificate for products. The results of steel fatigue and corrosion-fatigue tests were analyzed. The S-N curves in air and artificial seawater were constructed, and the corresponding values of endurance limits at room temperature and at 0 degrees C were also determined. A significant influence of the corrosive environment on fatigue crack propagation rate in steel was established.
