This work focused on the quality problems of steel caused by residual elements. The effects of tin with increasing amounts from 0.003% to 0.120% on the microstructure and mechanical properties of high carbon steels were investigated. The results indicate that the main microstructure of high carbon steels was sorbite. Sn has no influence on microstructure type but dramatically narrows the interlamellar spacing of sorbite, which increases from 0.24μm to 0.16μm with Sn contents increasing from 0.003% to 0.060%. It turns out that mechanical properties of these steels have a great relation with their interlamellar spacing of sorbite. The variation of strength and interlamellar spacing are in a good consistency, and the maximum values of yield strength and ultimate tensile strength are simultaneously obtained as Sn content is 0.060%. In order to obtain good comprehensive mechanical properties, Sn content should be less than 0.060% in high carbon steels.
