Studying the effects of changing speed and loads on wear resistance of (St37) Available to Purchase

Steel (St37) is a widely used metal in industries as it is lightweight, a good thermal conductor, and corrosion- resistant. It is also utilized to manufacture pipes, alloy wheels, and presses. In this research, the rate of wear was studied in two cases. First, the changed speeds with fixed both time, temperature, and load on the samples to study to which extent it affects the resistance to wear. Second, varying loads with constant time, temperature, and speed were used to examine the impact on wear resistance. It was found that changing speed in the wear test increases wear resistance and hardness with increasing the speed, so the wear rate of the metal decreases. When changing the loads, it was found that as the load increased, the wear resistance and hardness decreased while the wear rate increased.
