Abstract
Atomized steel powder having excellent machinability, containing about S 0.005 wt % to 0.3 wt %, Cr 0.03 wt % to 0.3 wt %, Mn 0.03 wt % to 0.5 wt %, O 0.30 wt % or less, and the balance Fe and incidental impurities, and sintered steel that can be manufactured therefrom. In particular, each of specific components is limited to a preferred range so that atomized steel powder exhibiting excellent machinability, dimensional accuracy and wear resistance and sintered steel that can be manufactured therefrom are provided.
