Product Description

Material Overview: Cobalt Alloy Valve Seats and Valve Balls are engineered for extreme environments. We provide materials based on specific customer chemical compositions or our standard high-performance material list.

Valve balls and valve seats are widely utilized in global oil fields.

Performance directly impacts the service life of sucker rod pumps.

Vacuum tested to ensure a perfect seal in all contact positions.

Key Features:

High Temperature Resistance: Maintains stable strength up to 800ºC; momentarily usable at 1200ºC.
Wear Resistance: Exceptional resistance to wear and galling due to the hard carbide phase in the CoCr alloy matrix.
Corrosion Resistance: Ideal for oil & gas, slurry, acid liquids, and aggressive mediums.
