The Effect of Water Corrosion and Shot Peening on Fatigue Strength of Mining Drill Rods

The results of research into the fatigue properties of SAE 1080 carbon steel and nickel-chromium-molylbdenum steel for mining drill rods are analysed and described in detail. The effect of water corrosion on the fatigue strength of drill rods of these two steels in the as-rolled condition has ,been 'investigated and the beneficial influence of shot-peening cm their dry and water-corrosion fatigue strengths determined by employing the method .developed previously (1) .
