Monel K-500 (UNS N05500) High Strength Nickel Copper Alloy Seamless & Welded Pipe Supplier

Monel K-500 (UNS N05500) Nickel-Copper Alloy Pipe

Monel K-500 pipe is a precipitation-hardened nickel-copper alloy that combines the excellent corrosion resistance of Monel 400 with significantly higher strength and hardness. With added aluminum and titanium, it achieves superior mechanical performance while maintaining outstanding resistance to seawater, sour gas, and harsh chemical environments.

Key Features

• ✔ Up to twice the strength of Monel 400
• ✔ Exceptional resistance to seawater and marine corrosion
• ✔ Excellent resistance to stress corrosion cracking
• ✔ High fatigue and erosion resistance
• ✔ Good dimensional stability across a wide temperature range
