FAQs
Q: What is wear resistant carbide plate?
A: Wear resistant carbide plate consists of an extremely hard tungsten or chromium carbide reinforcement dispersed in a metal matrix like nickel, iron or cobalt. This provides exceptional resistance to sliding, abrasive and erosive wear.
Q: What industries use wear resistant carbide plates?
A: Major industries using these plates include mining, cement, agriculture, food processing, pulp & paper anywhere high wear conditions are encountered in chutes, piping, fan blades, machinery parts etc.
Q: How long do carbide wear plates last?
A: Depending on the application and operating conditions, wear resistant carbide plates provide 5-10 times longer service life compared to regular steel. Life expectancy can reach thousands of hours before replacement is needed.
Q: Can you cut and machine carbide wear plate?
A: Yes carbide wear plates can be cut and machined using diamond abrasive slicing and grinding. Carbide is extremely hard so rigidity and specialized tooling is essential during machining.
Q: Should wear resistant plate carbide be sealed or coated?
A: In very corrosive environments, sealing or applying specialized coatings can enhance the functional life of carbide wear components and prevent chemical attack on the metal matrix binding the carbide particles.
