Cemented carbide content high-temperature carbide over high-speed steel, high hardness (HRC75--80), with good wear resistance.Cemented Carbide products include Carbide Nozzles
Hardness of High-speed steel can reach 650 degrees.
High-speed steel strength, toughness are good, sharpening cutting edge sharp, stable quality, generally used to create small, complex shape of the tool.
Hardness of Cemented Carbide can reach 800-1000 degrees.
Carbide Bars cutting speed 4-7 times faster than high-speed steel. High cutting efficiency.
The disadvantage is low bending strength, poor impact toughness, brittleness, to withstand the impact and low vibration resistance.
