Can carbide components handle the corrosive gases found in sour wells?
Yes, but material selection is critical. While tungsten carbide itself is highly resistant to corrosion, the cobalt binder used in many grades can be susceptible to attack by hydrogen sulfide (H₂S) and other acidic gases. For sour service applications, manufacturers often use specialized grades with alternative binders (like nickel) or apply specific grain structures. This ensures that the...
