Chromium in Steels – IspatGuru

Oct 08, 2014 · Role of chromium in stainless steels. The properties that distinguish stainless steels i.e. Fe-Cr-(Mo) alloys and Fe-Cr-Ni-(Mo) alloys from other corrosion resistant materials depend essentially on Cr. The high degree of reactivity of Cr is the basis for the effectiveness of Cr as an alloying element in stainless steels.

Chromium in Carbon, Alloy and Stainless Steels is Not

Oct 15, 2013 · The valency (oxidation state) of chromium metal as an alloying constituent of steels is zero (0). The chromium atoms are present in “substitutional” lattice positions, replacing iron atoms. These atoms are held in place in the lattice by shared electrons that make up a “metallic bond.”
