EFFECT OF PERIODIC NORMALIZING OF TRUCK SIDE FRAMES

The two series of tests on eight side frames covered by this report are the basis for the following conclusions: 1. Heat treatment of second hand truck side frames did not increase their fatigue life expectancy. 2. The reconditioning of worn column areas by welding when subsequently heat treated does not impair fatigue life expectancy. 3. The normalizing heat treatment process (heating to 1550 degrees F and cooling in still air) did not result in improved fatigue test performance in comparison with the stress relieving heat treatment as given the first four frames.
