A process for forming maraging steel alloys comprise forming an aqueous solution containing the metal values of iron, cobalt, nickel and molybdenum in a predetermined ratio, forming the reducible solid material from the solution, reducing the solid material to form metallic powder particles. These particles are entrained in a carrier gas and fed into a high temperature zone to form droplets. The droplets are cooled to form essentially spherical particles which are agglomerated with a predetermined amount of at least one readily oxidizable metal selected from the group consisting of aluminum, titanium and vanadium. The agglomerates are entrained in a carrier gas and fed into a high temperature zone to form droplets which are thereafter cooled to form essentially spherical shaped particles of a maraging steel alloy containing at least one readily oxidizable metal.
