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

Possible key metal monopoly committee's study. Washington, D.C., May 8. The temporary National Economic Committee turned its investigation today upon the little known beryllium industry. Senator Joseph O'Mahoney, Co-chairman of the Committee, is shown here with Andrew Gahagan, President of the Beryllium Corp., of Temple, Pennsylvania, examining the crude ore and a sample hammer which is made from an alloy with beryllium. Gahagan described beryllium as an element, fourth in atomic weight from hydrogen, which can be combined with copper or nickel and certain other metals, to produce alloys of extraordinary hardness, lightness, and strength. The committee suspects that the metal may become a key material in industrial and war supply problems

Back into production go these carloads of scrap metal, Allegheny Ludlum Steel[e] Corp., Brackenridge, Pennsylvania The melting of alloy steels for defense work requires that steel mill scrapyards such as this be constantly filled. The overhead magnet deposits the scrap in a loader which carries it to the open-hearth furnace. About 50 per cent scrap steel is used in open-hearth production

Possible key metal monopoly committee's study. Washington, D.C., May 8. The temporary National Economic Committee turned its investigation today upon the little known beryllium industry. Senator Joseph O'Mahoney, Co-chairman of the Committee, is shown here with Andrew Gahagan, President of the Beryllium Corp., of Temple, Pennsylvania, examining the crude ore and a sample hammer which is made from an alloy with beryllium. Gahagan described beryllium as an element, fourth in atomic weight from hydrogen, which can be combined with copper or nickel and certain other metals, to produce alloys of extraordinary hardness, lightness, and strength. The committee suspects that the metal may become a key material in industrial and war supply problems
