-7. (canceled)
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, wherein
- within a first stage of this atomization process, a stream of the molten iron-based alloy powder is fed through a nozzle into a first area located between the nozzle and a choke and a gas stream circulates around the molten iron-based alloy powder within this first area and,
- within a second stage of this atomization process, the stream of the molten iron-based alloy powder is fed to a second area located beyond the choke, where the stream of the molten iron-based alloy powder is contacted with a liquid jet stream under a pressure of at least 300 bar causing a break up and solidification of the stream of the molten iron-based alloy powder into individual particles of the iron-based alloy powder.
