Abstract: A steel composition is provided. The steel composition includes 0.02-0.45 wt. % carbon (C), 0-8 wt. % manganese (Mn), 0-8 wt. % nickel (Ni), 11-17 wt. % chromium (Cr), 1-3 wt. % silicon (Si), and a balance of iron (Fe). The combined concentration of the Mn and Ni is 2-8 wt. %. The steel composition is configured to form a surface oxide layer including oxides of at least one of the Cr or the Si after being subjected to press hardening. Press-hardened steel (PHS) fabricated from the steel composition and a method of fabricating a (PHS) component from the steel composition are also provided.
