Alloy UNS N05500 Round Bar with High-Strength, Corrosion-Resistant
UNS K500 round bar is a premium-grade nickel-copper alloy known for its exceptional combination of strength, toughness, and corrosion resistance. Engineered to withstand extreme environments, Monel K500 is an ideal material for critical applications across the marine, chemical, oil & gas, and aerospace industries. Its superior mechanical properties and resistance to seawater and sour gas make it a preferred choice for engineers and manufacturers seeking reliability and performance.
What is Monel K500 (UNS N05500)?
Monel K500 (UNS N05500) is a precipitation-hardened version of Monel 400. It is primarily composed of nickel (around 63%) and copper (approximately 30%), with additions of aluminum and titanium. These elements enable the alloy to undergo age hardening, significantly increasing its tensile and yield strength compared to its predecessor, Monel 400, while maintaining excellent corrosion resistance.
Key Features of Monel K500 (UNS N05500) Round Bar
Superior Strength: Through age-hardening treatment, Monel K500 round bars exhibit higher mechanical strength and hardness than non-hardened nickel alloys.
Excellent Corrosion Resistance: Particularly resistant to seawater, salt spray, and a wide range of acidic and alkaline environments, making it ideal for marine and chemical processing applications.
Non-Magnetic: In the annealed condition, Monel K500 is non-magnetic and remains so even at sub-zero temperatures, which is crucial for applications requiring minimal magnetic interference.
Outstanding Wear Resistance: The addition of aluminum and titanium also enhances the alloy’s wear and erosion resistance, making it suitable for high-friction environments.
Long-Term Stability: Maintains mechanical integrity and corrosion resistance over long operational periods, even under harsh environmental conditions.
Applications of Monel K500 (UNS N05500) Round Bar
Monel K500 round bars are used in a wide variety of high-performance and high-pressure environments, including:
Marine Engineering: Propeller shafts, pump shafts, and seawater valve components
Oil & Gas Industry: Drill collars, valve components, and instruments exposed to sour gas
Chemical Processing: Equipment for handling sulfuric acid and hydrofluoric acid
Aerospace: Engine components, fasteners, and structural parts requiring strength and corrosion resistance
Nuclear Applications: Components exposed to radioactive and corrosive environments
