摘要:: 随着国内海洋装备制造业的快速发展，海外项目日益增多，越来越多的欧洲标准钢材被用于海洋工程领域。通过解读欧标钢材的分类及标记，总结海工领域所使用的欧洲钢材标准，有利于掌握欧洲系列钢材标准，从而推动海洋工程装备制造业的发展。同时进一步阐述了欧标与国标钢材替代的基本原则，并分析了欧标结构钢材与国标的区别，发现欧标结构钢材和国标结构钢材并不能等效对应。国内海洋工程制造企业及钢材供应企业应该积极推动海洋工程用钢专用国家标准的发展，提升国产高强钢的应用范围。

Abstract:: With the rapid development of domestic offshore equipment manufacturing industry and the increasing overseas projects, more and more European standard steels are applied in the field of offshore engineering. In this paper, the classification and sign of European standard steels are introduced and the European standards used in offshore engineering fields are summed up. These will help master steel standard for European series and promote the development of offshore engineering equipment manufacturing industry. Moreover, the basic principle of substitution between European standard steel and National standard steel is put forward, the differences between European standard structural steel and GB standard structural steel are analyzed, the two series of steel cannot be equivalent. The domestic offshore engineering manufacturing enterprises and steel manufacture enterprises should actively promote the development of the special national standard for the offshore engineering steel, and improve the application range of the domestic high strength steel.
