Abstract
A low-sulfur granulated metallic unit having a mass fraction of sulfur between 0.0001 wt. % and 0.08 wt. % is disclosed herein. Additionally or alternatively, the granulated metallic unit can comprise a mass fraction of phosphorous of at least 0.025 wt. %, a mass fraction of silicon between 0.25 wt. % and 1.5 wt. %, a mass fraction of manganese of at least 0.2 wt. %, a mass fraction of carbon of at least 0.8 wt. %, and/or a mass fraction of iron of at least 94.0 wt. %.
