Carbide Properties
Cemented carbide products have excellent mechanical and physical characteristics. Abrasion Resistance Carbide's exceptional resistance to abrasion is its most important property. In abrasive applications, carbides can outlast some wear-resistant steel alloys by a factor of 100 to 1. Deflection Resistance Cemented carbides have a high modulus of elasticity that provides minimum deflection when exposed to bending forces. In fact, the modulus of elasticity is three times that of steel. Corrosion Resistance Since carbides are generally chemically inert (considering binding material as a factor), they can be used successfully in many chemical and corrosive environments. Torsional Strength With a torsion modulus twice that of high-speed steel, carbide is the preferred material for rotating applications. Compressive Strength Some grades of carbide with cobalt binder perform flawlessly under ultra-high compression and have been used very successfully in pressure applications at up to one million psi. Toughness Carbide grades with higher binder contents have excellent resistance to impact. Low Temperature Wear Resistance Even at cryogenic temperatures as low as -453°F, carbides retain good wear resistance and offer a relatively low coefficient of friction where lubricants cannot be used. High Temperature Wear Resistance At 1,000°F, carbides still maintain over 90% hardness. Certain grades can even retain significant strength at 2,000°F (higher at intermittent temperatures). |
