...miner, Mauricio Hochschild, took sides. Hochschild went to the U. S. last winter, contracted with Phelps Dodge Corp. to supply tin for its new experimental smelter (TIME, Dec. 11). Meanwhile American Metal Co. Ltd. and American Smelting and Refining Co. also built pilot plants, and learned how to process Bolivian ore (which is high-cost, low-grade) with no admixture of Malayan. By last week it was pretty clear that, besides accumulating a 75,000-ton stockpile of smelted tin, the U. S. must be prepared (in case Britain and Malaya go under) to smelt Bolivian...
...again. Awarded to Anaconda by the new Government-owned Metal Reserve Co. was a contract for 240,000 tons of manganese, to be delivered at the rate of 80,000 tons a year. Most heartening news of all was Anaconda's announcement that it had a selective-flotation process for working the ore, that its concentrate would be as high-grade as any bought abroad. Anaconda will put $1,500,000 into a new plant, will be able to produce 100,000 tons a year, take at least one-eighth of their manganese worries off the shoulders...
Last year Oscar Bach announced he had hit upon a process for coloring tough, corrosion-resistant 18-8 (18% chromium, 8% nickel) stainless steel. In the Bachite process, the steel is first "pickled" (cleaned with acid), then coated in a chemical bath and heated. Depending on the degree of baking, the coated steel turns black, gold, bronze, purple, blue, red or green, the color becoming an integral part of the surface. Oscar Bach will not reveal the chemicals in the coating bath. "The formula," says he, "is so simple I'm almost ashamed of it." The Bachite process...
...Oscar Bach began working with less expensive iron & steel alloys, he found to his surprise that his coloring process immensely improved corrosion resistance. Last week the "American Cellini's" researches led him to the threshold of National Defense. He announced a process for Bachiting cheap black plate iron (3? per lb.), which, he claims, makes the metal a substitute for tin plate. Tin is important in tin cans because it resists corrosion by food acids. Bachited iron, said Bach, had a corrosion resistance against "most corrosive agents" higher than that of tin plate...
...shells, A. C. F.'s Berwick plant boss, spectacled, trap-mouthed Guy C. Beishline built three new plant additions, started an ordnance department, filled it with annealing hearths, lathes, other machine tools. A. C. F.'s flint-shelled armor plate for tanks is made by a secret process, involving endless steel treating and hardening, and Guy Beishline's workmen work around the clock, seven days a week...
