Regression Analysis on Effect Between Mechanical Properties and Arsenic Content in Steel

The effect rules were analyzed between the mechanical properties and arsenic content in 60Si2MnA steel,using linear regression method. The results showed that tensile strength,yield strength and elongation ratio after broken had certain linear relations with arsenic content;With the increasing of arsenic content,the tensile strength and yield strength ascended,but the elongation ratio after broken descended;In order to ensure elongation ratio after broken exceed 6.5%,arsenic content needs to be controlled under 0.016 0% in producing process.
