Staybolt material in the storeroom represents a relatively sm'3Il cost per bolt. ,. ,. Forged. threaded and- applied, .1S a replacement in a 1ocomotive, it represents more than a dollar in actual cost. .. In many cases the out<lf service cost for the locomotive must be added to this. .. Yet between the poorest stay bolt material and the best there is a negligible difference in material cost. The use of
Agathon Alloy Staybolts keeps renewal costs at a minimum. Agathon Staybo1l Steel has high tcn..<;.ilc !;\ rength, high resistance to fatigue, and high resistance to corrosion. .. .. ,. It with stands the high pressures, the constant vibration and weaving of the firebox. It gives longer service at lower costs. ,. .. Specify Agathon Staybolt Stel for your difficult jobs.
