Patent Abstract

The present invention relates to the fields of materials science and concerns an additional material that can be used in surfacing welding in vehicle, machinery and plant engineering. The object of the present invention is therefore to provide an additional material that, as a material in surfacing welding, leads to a deposited layer whose mechanical and thermal strengths are significantly improved. The object is achieved by an additional material consisting of a high-strength iron alloy with a composition according to the formula Fea E1b E2c E3d with E1 one or more elements from the group Cr, V, Mn, Co, Ni, E2 one or more elements from the group Mo, W, Cu, Ti E3 one or more elements from the group C, N, B, and with a = 100 – (b + c + d) b = 0.1 to 12 c = 0 to 12 d = 0.001 to 25 (a, b, c, d in atomic %), and with a microstructure consisting at least of
