摘　　要：归纳了海洋石油平台用钢的类别品种,包括一般强度钢、高强度钢、超高强度钢,以及耐海水腐蚀低合金钢、齿条钢、Z向钢、适合高热输入焊接钢、高强度系泊链钢、高强度铸钢等特殊用途钢种;分析了海洋平台用钢的标准体系,并介绍了欧洲标准、API标准、船级社标准以及国家标准对平台用钢的性能要求;综述了国内外平台用钢的产品开发及应用现状;最后讨论提出了海洋石油平台用钢向高强、高韧以及良好低温韧性与焊接性方向发展的趋势。The main varieties and specifications of offshore platform steels are summarized,which include general strength steel,high strength steel,ultra-high strength steel and special purpose steeling（ seawater corrosion resistant low alloy steel,gear steel,Z-direction steel,high heat input welding steel,mooring chain steel and high strength cast steel,etc.）. The standard system of platform steels and the relevant requirements of European standards,API standards,classification society standards and national standards are concluded. Then the RD status of platform steels are discussed. Lastly,the development trends of offshore platform steels are pointed out.
