检测了冷拉高强Cr-Ni-Mo不锈钢绞索的力学和物理性能；并从实验室研究和项目跟踪观察两方面介绍高强度不锈钢绞索的抗腐蚀性能；最后，展望了高强度不锈钢绞索在桥梁工程方面的应用.
Bridge cables are supposed to take the high tensile force with relatively small cross-section.Conventionally bridge cables are made of unalloyed and/or low-alloyed steel ropes.Regarding a long durability application of high-strength stainless steel strand is considerable.In Germany,cold-drawn stainless steels are produced about 25 years since,which possess comparable characteristics in strength and deformation with conventional high-strength steels.In this contribution the cold-drawn high-strength strands,which are made of Cr-Ni-Mo-steels,are investigated in respect of their mechanical and physical properties,as well as their corrosion behavior in atmosphere.At the end,the application of high-strength stainless steel strands is suggested to be extended to the field of prestressed concrete structures,regarding their high corrosion resistance and good workability.
