Abstract: The smelting process of the new tincontained ferritic stainless steel was studied based on metallurgical reaction balance under laboratory condition. The yield of tin in the melting process of the stainless steel and the effects of the addition of tin on the microstructure of stainless steels were analyzed. The formation and evolution of inclusions formed in deoxidation process of molten stainless steel were also analyzed. The results showed that the yield of tin was pretty high regardless of its low melting point. The enrichment of tin around the sulfide inclusions was found in scanning electron microscope pictures and it is white in SEM, while it was not found in or around the oxide inclusions. From the metallographic analysis, tin segregated to the grain boundary when its content was higher than 0.3%.

Key words: tin, ferritic stainless steel, microstructure, inclusions, segregation
