Monel K500 Bar/Rod/Wire/Forging/Plate/Strip UNS N05500 2.4375 Non-Magnetic Ideal for Stress Corrosion Cracking and High-Stress Applications

Monel K500 (UNS N05500, W.Nr. 2.4375) is a nickel-copper alloy with enhanced strength and hardness due to aluminum and titanium additions. It offers excellent corrosion resistance, particularly in marine and chemical environments, while maintaining superior mechanical properties at high temperatures. The alloy is precipitation-hardened, improving yield and tensile strength over Monel 400.

Monel K500 is available in various forms, including bar, rod, wire, forging, plate, and strip, making it suitable for marine engineering, oil and gas, aerospace, and chemical processing. It resists chloride-induced stress corrosion cracking and retains ductility even in cryogenic conditions. Common applications include pump shafts, valve components, springs, and fasteners. It is widely used where strength and corrosion resistance are critical.
