The impact of mechanical seal material hardness on wear resistance:

The impact of the hardness of the container John Crane 502 mechanical seal on the wear resistance is generally that the higher the hardness, the smaller the wear. Experimental studies have shown that the hardness of mechanical seal materials and alloys is the main factor affecting wear resistance, and the relative wear resistance of various materials (under the same test conditions, the amount of wear of the standard material and the amount of wear of the tested material is ratio). For pure metals and annealed steel, there is a linear relationship between relative wear resistance and hardness.　　411.html,
