摘要： 基于新型含锡铁素体不锈钢，采用冶金反应平衡对其冶炼过程进行实验室条件下的研究，对其室温力学性能、耐腐蚀性能进行了研究，同时分析Sn对铁素体不锈钢基体的微观结构的影响规律，分析脱氧夹杂物的形貌和成分演变.研究结果表明，尽管锡的熔点极低，其收得率较高，锡在硫化物周围的富集现象明显；含锡铁素体不锈钢性能优于SUS430不锈钢，具有较好的塑形和强度，可满足深冲加工性能的要求，而耐腐蚀性能明显优于SUS430铁素体不锈钢，可部分代替其在生产中的应用.

Abstract: The mechanical properties， the corrosion resistance and the effect of Sn on the microstructure of the Sncontaining ferritic stainless steel matrix were studied on the basis of the metallurgical reaction equilibrium of the smelting process. The morphology and composition evolution of the deoxidization inclusions were analyzed. The results showed that the yield of tin is pretty high in consideration of its low melting point. The enrichment of tin around the sulfide inclusions is observed in scanning electron microscope. The new type ferritic stainless steel has better corrosion resistance than SUS 430 stainless steel， and the excellent plasticity and strength which can meet the requirement of deep drawing process. Therefore，it can substitute partly the application of SUS 430 in the industrial production.

Key words: tin, ferritic stainless steel, microstructure, inclusions, corrosion resistance
