Study on Properties and Inclusion of Environmental Automatic Steel Alloyed with Tin Element

Abstract:

A new environment-friendly automatic steel alloyed with tin element Y20Sn has been developed. In test, new steel possess good machinability and mechanical property, which reach Chinese National Standard of corresponding automatic steel GB/T8731-88. In steel, the shape of inclusions is mainly spherical or spindly, which volume is small and distribution is evenly. Such style of inclusion can fairly improve the steel machinability, and doesnt impair its mechanical property at the same time. As the main inclusion in developed automatic steel, MnS inclusion is one important factor which influences the machinability of steel. In the steel alloyed with tin, tin exist around MnS inclusions or are attached to MnS inclusion will influence the formation mechanism of MnS inclusion, that is the important reason why tin element influence machinability of developed automatic steel Y20Sn.
