Show FIND USES FOR METAL IN STEEL MAKING Development of new uses for molybdenum, of which the Utah Copper company at Bingham is the second largest producer in the world, is continually lessening this country's dependence on outside out-side sources of steel-hardening materials. "This metal,' neglected for many years, - is now playing a leading role in steel making as a result of the industry's search for substitutes tp replace metals formerly obtained abroad," Dr. A. A. Bates, manager of the chemical chem-ical and metallurgical departments depart-ments of the Westinghouse research re-search laboratories, Pittsburgh. "This country is rich in its resources re-sources of base metals iron, aluminum, al-uminum, lead, zinc and copper," he continued. "But we have already al-ready had to depend upon supplies sup-plies from abroad for nickel, chromium, manganese and tungsten, tung-sten, which are used with iron to produce steel of strength, hardness, hard-ness, toughness or woorkability."

Molybdenum, sametimes called the "Cinderella metal," is a latecomer late-comer to the production line, partly because the nation's great stores of it were discovered in comparatively recent years and partly because of difficulties metallurgists had to overcome in learning to produce and heat-treat heat-treat alloys containing molybdenum, molybde-num, Dr. Bates explained. The Climax Molybdenum company com-pany in Colorado is the world's No. 1 producer. For the past few years the Utah Copper company has recovered molybdenite as a by-product from its copper ore. Last year the big Bingham mine produced around 9,000,000 pounds of molybdenum metal as a byproduct by-product of its huge 514,000,000 pound copper production. Equal in Quality Westinghouse is now using molybdenum and chromium in place of nickel as the strengthening strengthen-ing agent in steel for shafts, belts, gears and other highly stressed parts for such machines as motors and generators. When tungsten was added to the list of strategic materials, Westinghouse needed a substitute for highspeed high-speed tool steel, which contains about 18 per cent of this metal. A substitute was found in molybdenum moly-bdenum steel containing only a few per cent tungsten. The new alloy is equal in quality qual-ity to its predecessor and is less expensive. Engineers say that if it proves as good in operation as they think it will, Westinghouse will never return to the use of I straight tungsten tool steel for |
