Fatigue Life Test

Consumption Contrast Figure of TAA LCB steel shot, low-carbon steel shot and high-carbon steel shot.(fatigue life test of normal grades at an impacting speed ratio of 60.96m/s)

Consumption contrast-Normal grade

Low Carbon Steel Shot2
Low Carbon Steel Shot3

Through the fatigue life test we can see that: the service life of TAA LCB Steel Shot is 1.5 times longer than common low carbon steel shot, 2 times longer than high carbon steel shot.
