  • This study examined the effects of the tempering temperatures($360-420^{\circ}C$) on the mechanical properties of the carbon tool steel (SK4M) for flat spring. Hardness test, tensile test and fatigue test were performed at room temperature($20^{\circ}C$). The tensile strength and yield strength of $390^{\circ}C\;and\;420^{\circ}C$ tempered SK5M were 0.93-0.97 times and 0.81-0.87 times those of $360^{\circ}C$ tempered SK5M, respectively. The fatigue limit of $360-420^{\circ}C$ tempered SK5M were 35-40% of tensile strength of $360-420^{\circ}C$ tempered SK5M, respectively.
