This invention is an improvement in a method for producing alloy steel which may contain, for example about 1.00% carbon, about 0.45% manganese, about 0.25% silicon and 1.50% chromium. The steel has a lower incidence of nonmetallic inclusions than steel produced in a conventional method, for example an air-melt electric furnace, open hearth. The steel is melted and tapped and then vacuum treated by any one of several well-known methods. The steel is deoxidized and a fluoride-containing acid slag is added to the steel. The steel and the slag are intimately mixed. The steel is then teemed into molds which can be relatively large.
