Abstract

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
