MACH13 HOB
This dissolution HSS boosts performance of resistance for the chipping
Characteristics
- 1.The fine particle with uniform placement enhances the chipping resistance.
- 2.Strengthening of substrate with salt heat treatment performs the resistance against chipping and wear.
- 3.It enhances the cutting face smooth due to the sharp cutting edge of the tool.
Chipping resitance
Structure after general heat treatment | Structure after MACH13 heat treatment |

Carbides precipitation at the boundary of matrix. It is easy to chip because the bond between particles is weak, also Abrasion resistance is reduced because carbides do not dissolve in the matrix. | No carbides precipitation at matrix boundaries. The strong bond between the matrix makes it difficult to chip, and the carbides dissolve in the matrix to improve wear resistance. |
