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.
