If you're going to wholesale cheap chromium carbide (crc) valve ball made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Product Overview
Chromium carbide valve balls are high-performance sealing spheres for industrial ball valves, which adopt advanced surface modification technology to deposit a dense chromium carbide (CrC) hardened coating on the metal base. With surface hardness up to HRC 60-70, this product integrates superior wear resistance, corrosion resistance and scouring resistance, effectively resisting the erosion of solid particle carriers and the corrosion of chemical media. It is a specialized sealing component tailored for high-pressure, heavy-wear and corrosive industrial pipeline systems, ensuring long-term stable operation under severe working conditions.

Frequently Asked Questions
What is the bonding strength of the chromium carbide coating?
The chromium carbide coating is tightly combined with the metal base through professional process treatment, with high bonding strength, not easy to fall off or crack during long-term use.
Can it be used for highly corrosive chemical media?
Yes, the chromium carbide coating has excellent corrosion resistance, which can stably resist the corrosion of most acid, alkali and salt chemical media.
How to ensure the sealing accuracy of valve balls?
We adopt high-precision grinding and polishing technology, with coaxiality ≤0.05mm and roundness ≤0.02mm, to ensure precise matching with the valve seat and reliable sealing.
What factors affect the service life of chromium carbide valve balls?
The main factors include medium properties, operating pressure, temperature and use frequency. Selecting matching materials can effectively extend the service life.
