MITSUBISHI CARBIDE GRADE FOR WEAR RESISTANT TOOLS
Sub-Micro Grain Series
This sub-micro-grain series is produced by our own unique technology. Utilizing its excellent wear resistance due to high hardness and high compressive strength, the series is widely used for Slitting Knives and other
special wear-resistant applications.
GC Series
Superior in fatigue resistance and corrosion resistance as well as in shock resistance and wear resistance.
GTi Series
Used for general wear-resistant applications. This series can maintain high hardness, but high modulus of elasticity and high compressive strength even at high temperatures. The series offers various wear-resistant tools and machine parts.
