Zusammenfassung:	An alloy composition is provided. The alloy composition includes chromium (Cr) at a concentration of greater than or equal to about 0.5 wt. % to less than or equal to about 9 wt. %, carbon (C) at a concentration of greater than or equal to about 0.15 wt. % to less than or equal to about 0.5 wt. %, manganese (Mn) at a concentration of greater than or equal to about 0 wt. % to less than or equal to about 3 wt. %, silicon (Si) at a concentration of greater than or equal to about 0.5 wt. % to less than or equal to about 2 wt. %, and a balance of the alloy composition being iron. Methods of making shaped steel objects from the alloy composition are also provided.
