BN - K1 SNMN120404 Solid CBN inserts Processing Mud pump with better impact resistance
1. Halnn Tools BN - K1 SNMN120404 Solid CBN inserts Processing Mud pump with better impact resistance
Because of the harsh environment of the industry pump, the usage life is short. In order to extend high tool life and high wear resistance, the manufacturers usually choose High chromium cast iron with high hardness, strength as the main materials for industry pumps, such as Cr15Mo3, Cr15Mo2Cu,Cr26,etc.
The castings made of High chromium will have high hardness, large working allowance, and also have some defects, which made it difficult to machine.
