Abstract

This paper aimed to investigate the advantages of the use of S700MC steel instead of St52 steel widely used in industrial areas. For this purpose, a tensile test, a macro hardness test, a Charpy impact test, and a fatigue life test were performed on St52 steel and S700MC steel specimens. Test results showed that S700MC steel generally exhibited better performance than St52 steel in terms of mechanical properties and fatigue life. In addition, a finite element method (FEM) analysis was conducted on a tandem housing body of a motor grader according to S700MC and St52 scenarios to determine their safety factors and the reduction in its weight with the use of S700MC steel. FEM results showed that the use of S700MC steel led to an increase in the safety factor by about 83 % or a decrease in the weight by about 30 %.
