Abstract

The invention relates to an iron based material for coating of surfaces which comprises a binding phase in the form of a corrosion dense alloy which contains at least 50% Fe, 12-30% Cr, maximally 5% Mn, 0-40% Ni, preferably 6-20% Ni and 0-7% Mo and 0-1% N and 6-20% Si, all stated as weight percent, which addition of Si lowers the liquidus temperature, that is the temperature at which the binding phase is completely melted. The invention also aims at products of metal coated with the iron based material mentioned above.
