BÖHLER K888 MATRIX is an excellent combination of high toughness and high compressive strength. MATRIX materials have high toughness, which is a critical factor in many applications. However, the achievable hardness with conventional MATRIX steels often limits the potential uses. 

BÖHLER K888 MATRIX combines the benefits of conventional matrix steels and high-alloyed tool steels. The combination of high compressive strength and minimal internal defect size (primary carbides) significantly increases the fatigue strength. This results in a significant reduction in fatigue failures and longer tool life.

With its high compressive strength and the resulting high supporting effect, BÖHLER K888 MATRIX is an optimal substrate for innovative coatings. 

Properties and benefits:

» Excellent toughness and ductility result in high resistance to fracture and chipping.
» Hardness: > 64 HRC
» High compressive strength
» Good machinability
