TheChalmers Heat Treating Department, Drawn from life by H. L. Grout No Guesswork The broken edge of a Chalmers gear will cut glass; it is diamond hard. A Chalmers front axle or steering arm can be bent double without breaking; it is tough as green oak. Chalmers valves will endure severest heat without warping or pitting; they are Tungsten steel, the hardest that can be made. These are some of the reasons why Chalmers heat-treated parts were two years ago judged the best of any exhibited at the convention of American Master Blacksmiths. Why last year Chalmers heat-treated steels, in competition with the product of the biggest and best manufacturers of steels in America, were again declared best by the American Master Blacksmiths. Such uniform quality is not the result of chance. The Chalmers heat-treating department is one of the largest in the automobile industry. Every furnace is of the latest construction. Every treatment, whether for toughening or hardening, is scientific. All are tested time and again to prove their beneficial results. Every operation is controlled by electric pyrometers-or heat gauges. There is no guesswork in Chalmers heat-treating. That is why Chalmers heat-treated parts are voted best by the American Master Blacksmiths. That is why Chalmers cars are the choice of over 40,000 owners. That is why the 1915 Chalmers "Sixes" are the fastest selling cars we have ever built. Chalmers "Doings" Number 45 gives complete information about the 1915 cars. Write for it.
