Metallic bonding which  differs from covalent bonding in that metallic bonding is non directional and non local. The valence electrons are diffuse and shared among the entire network  of metal atoms because the energies of the valence electrons are very similar.

how about bonding between non-metallic elements inside the stainless steel, such as carbon (to strengthen its structure)?

It's still metallic bonding as nonmetals sit in interstices in a "solution" of metal. The non metals present local diruptions to the valence metal electrons.
However, non metals can also microsegregate with metals to produce distinct phases like Fe3C in which case the bonding is localized polar/covalent bonding.
