ABSTRACT:
A steel flake product, suitable for being crushed or ground to form a steel powder for powder metallurgical purposes, consists of a plurality of relatively thin, brittle and easily crushed, substantially dendrite-free steel flakes of amorphous to compact-grained structure. Such steel flakes are produced by causing molten steel to form at least one discrete, relatively thin flake-shaped layer on a relatively cold metal surface of great cooling capacity, moving rapidly and substantially across the direction of delivery of the molten steel. Due to the great cooling capacity the layer is made to solidify extremely rapidly.
