Abstract: The present invention relates in a first aspect to an iron-based alloy powder containing non-spherical particles and at least 40% of the total amount of particles have a non-spherical shape. The alloy mandatorily comprises the elements Fe (iron), Cr (chrome) and Mo (molybdenum). Furthermore, the alloy may comprise further elements such as C (carbon), Ni (nickel), Nb (niobium) or Si (silicon). The present invention relates, according to a second aspect, to an iron-based alloy powder wherein the alloy comprises the elements Fe, Cr and Mo and the iron-based alloy powder is produced by an ultra-high liquid atomization process comprising at least two stages as defined below.

Abstract: The present invention relates to an iron-based alloy powder containing non-spherical particles wherein the alloy comprises the elements Fe (iron), Cr (chrome) and Mo (molybdenum), and at least 40% of the total amount of particles have a non-spherical shape. In said iron-based alloy powder, Cr is present at 10.0 wt. % to 18.3 wt. %, Mo is present at 0.5 wt. % to 2.5 wt. %, C is present at 0 to 0.30 wt. %, Ni is present at 0 to 4.0 wt. %, Cu is present at 0 to 4.0 wt. %, Nb is present at 0 to 0.7 wt. %, Si is present at 0 to 0.7 wt. % and N is present at 0 to 0.20 wt. %, the balance up to 100 wt. % is Fe.
