What is ASTM B564 Monel K500 (UNS N05500)?
Monel K500 (UNS N05500) is an advanced nickel-copper alloy enhanced with aluminum and titanium. This combination allows it to be hardened through heat treatment, giving it:
- Higher tensile strength
- Improved hardness
- Excellent resistance to corrosion and erosion
- Stability in extreme environments
This makes monel k500 high strength flanges for marine applications highly reliable in seawater and offshore conditions.
