摘　　要：概述了世界范围内特超级双相不锈钢的发展现状及趋势,重点对特超级双相不锈钢的成分设计思路、组织特点进行了分析,并结合其性能优势介绍了国外在相关领域的应用范例。强度更高、耐蚀性能更优的特超级双相不锈钢正在成为新一代的双相不锈钢材料,其将在海洋工程、石油石化、化工等领域获得广泛的应用。The development status and trend of hyper duplex stainless steels （HDSS） around the world were over- viewed. Moreover, the alloy design, microstructure characteristics of HDSS were mainly analyzed, and the new application fields of HDSS were introduced. Benefited from the outstanding corrosion resistance and higher strength, hyper duplex stainless steels have become new grades of DSS and will have broad application in the areas of marine engineering, petroleum and chemical industry in the future.
