(Continued on page 1461 - POWER Stptamb*, When you specify Monel for pump shafts, ft/ you get the combination of qualities needed to combat severe service conditions of wear, .stress, vibration, corrosion, and heat. Monel : insures against frequent, costly replace ments; cuts maintenance overhead. For help in solving metal selection problems, send for your INCO NICKEL ALLOYS SELECTOR. This handy slide-rule-type chart tells you at a glance which of the versa tile Inco Nickel Alloys will best serve your requirements. Remember..,Monet has ell these features: a High resistance to corrosion, corrosionfatlguo, and stress-accelerated corrosion; THE `-INTERNATIONAL NICKEL .COMPANY, INC. ,r w.ll lrn.1,.rtf T.i* S.X. T. . Exceptional hardness, which means less wear at bearings and journals. High resistance to fatigue caused by stress, vibration, end pulsation. a Strength equal to that of steel. And if you need special properties, there is"Jt"Monef for high-speed production machining; "K" Monel that is neat-treatable to tensile `bongth higher than 150,000 P*l; "KK" Monel that Is both ree-machining and heatheatable. MONEL solved these difficult problems-- Case t. In a large metropolitan power plont, the mild atcel . shaft of a huge circulating pump failed repeatedly because of corrosion-fatigue. Several other metals, were tried.without success. Then engineers called forMK" Monel. The result was tho world's lergeet high Nickel elloy pump shelt--13'x9'*dia.! Casa 2. A pump manufacturer had difficulty making long, thin shafts for multi-ctege high pressure pumps. Stresses set up during machining caused the shafts to deform and fall in Berviee. Heat-treatable "K" Monel was'tried --and proved to be the solution to this problem, too. I MO,Nil' H'"M0"U "S'"MOM l "MO Nil "WR" * MO HI l IN COM I* NtChll "l'" NICK It "r`*NICMl 1949 141
