Steel alloy manufacture. Allegheny Ludlum Steel Corporation, Brackenridge, Pennsylvania. Thirty-five ton electric arc melting furnace in operation. These furnaces convert scrap iron and steel into high quality steel alloys. This type of furnace gives much faster heating and permits the accurate temperature control so necessary in the processing of the high quality steels. The alloying elements are being added to the bath of molten steel
