Abstract:  
This investigation was undertaken to find out how various shot hardness will affect the endurance life. As a matter of interest, attempts were made to determine the possibility of overpeening springs even using shot know to be large for the wire size in the spring. On all tests Almen strips were included with the springs. If correlation of the Almen arc height and spring life were possible, the tests run would establish this fact.
