摘　　要：对基于“混杂”设计的索氏体高强新型不锈钢进行了显微组织分析及力学性能和耐腐蚀性能评价;进一步将其与其他典型钢种对比,并探讨其应用前景。结果表明:索氏体不锈钢显微组织类型上与马氏体不锈钢相似;具有较好的强韧性匹配,并且调控范围广;成形性和冲击性能良好;耐蚀性与201奥氏体不锈钢相当或比201奥氏体不锈钢略差,但比410马氏体不锈钢略好;索氏体不锈钢在耐蚀工程结构等领域具有广阔的应用前景。Microstructures,mechanical properties and corrosion resistance of a new high-strength sorbite stainless steel were analyzed and evaluated,which was designed based on the concept of“hybrid”.Furthermore,the sorbite stainless steel was compared with other typical steels and its application prospects were discussed.Results showed that the microstructure of sorbite stainless steel was similar to that of the martensitic stainless steel.The strength and toughness of the sorbite stainless steel matched well and could be regulated in a wide range.The formability and impact properties were favorable as well.The corrosion resistance of the sorbite stainless steel was comparable to or slightly worse than 201 austenitic stainless steel,while it was slightly better than 410 martensitic stainless steel.Therefore,the application prospects of the sorbite stainless steel is board in the field of corrosion-resist structural engineering.
