Abstract

An iron-based alloy that is able to provide a coating on a substrate, the coating having simultaneously high hardness, corrosion resistance and bonding strength to the substrate. The iron-based alloy has 16.00-20.00% by weight Cr; 0.20-2.00% by weight B; 0.20-4.00% by weight Ni; 0.10-0.35% by weight C; 0.10-4.00% by weight Mo; optionally 1.50% by weight or less Si; optionally 1.00% by weight or less Mn, optionally 3.90% by weight or less Nb; optionally 3.90% by weight or less V; optionally 3.90% by weight or less W; and optionally 3.90% by weight or less Ti; the balance being Fe and unavoidable impurities; with the proviso that the total amount of Mo, Nb, V, W and Ti is in the range of 0.1-4.0% by weight of the alloy.
