Stellite, Metal That Will Not Rust—Hardness and other Qualities of Steel

Everybody knows that metals under go changes through the influence of oxygen and moisture from * the air—these two bodies being always ready for chemical business. Therefore, as everybody also knows, steel knives and other familiar utensils require continual cleaning because they rust so easily. Steel is eyen more susceptible to rust than Iron. The chemists’ problem In this case has been to make a metal which is permanent and will not rust, having, at the same time, the hardness and other qualities of steel. That is, a metal as “noble” or permanent as gold and as herd and strong as steel. Elwood Haynes, a member of the American Chemical society, relates in Metallurgical and Chemical Engineering of a long series of experiments which he made during a period of many years, especially In alloys of cobalt, chromium, tungsten and molybdenum. He finally succeeded in making some of these metals so hard that they can scratch any steel in existence. He has given the name stellite to the series. Stellite may be Indefinitely heated without showing oxidation, except for the fact that the surface takes on a permanent blue color. Lathe tools, milling cutters, saws, drawing dies, boring tools, drills, etc., have been made from stellite as well as surgical and dental Instruments which have been placed on the market. Tablespoons and small spoons of stellite have been in use for six years and they may last, it appears, for a thousand years more without tarnishing.
