摘要

本文介绍了质量等级为 Q420B 的 Q420 钢样品的一系列实验测试结果。钢的化学成分及其机械特性（在产品证书中标明并通过实验确定）与产品证书中的标准值进行了比较。分析了钢疲劳和腐蚀疲劳试验的结果。构建了空气和人工海水中的 S-N 曲线，并确定了室温和 0°C 下的相应耐久极限值。确定了腐蚀环境对钢疲劳裂纹扩展速率的重要影响。

Mechanical Properties of Steel for Floating Offshore Platforms under Static and Cyclic Loading

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°C were also determined. A significant influence of the corrosive environment on fatigue crack propagation rate in steel was established.
