Abstract
For providing laser cladded surfaces with low cracking risk in the laser cladded surface, whether macro or micro cracking, an iron-chromium based alloy is provided, consisting of by weight of total weight of alloy: Chromium (Cr) : 20.5 wt %-28.0 wt %, Nickel (Ni) : up to 5.0 wt %, Silicon (Si) : 0.5 wt %-2.5 wt %, Boron (B) : 0.50 wt %-1.5 wt %, Molybdenum (Mo) : 0.15 wt %-2.0 wt %, Manganese (Mn) : 0.10 wt %-0.90 wt %, Carbon (C) : 0.01 wt %-0.20 wt %, Niobium (Nb) : up to 1.5 wt %, Copper (Cu) : up to 0.2 wt %, Cobalt (Co) : up to 1.0 wt %, the balance being iron (Fe) and unavoidable impurities not exceeding 0.3 wt %.
