Method of manufacturing iron powder and iron powder manufactured thereby
A method of manufacturing iron powder configured for improving a recovery rate of chromium using ingot including chromium in a content suitably higher than a target content at the time of manufacturing iron powder including chromium, may include preparing ingot further including chromium (Cr) so that a content of chromium (Cr) in the ingot is 1 to 30% higher than a target content of chromium (Cr) in finally produced iron powder; dissolving the ingot to prepare molten steel; forming iron powder by performing water atomization on the molten steel; and adjusting a content of carbon (C) in the iron powder by performing reduction treatment on the iron powder.
