Strong Monel K500 UNS N05500 2.4375 Bolt For Harsh Marine And Offshore Applications

Monel K500 (UNS N05500, 2.4375) bolts are high-strength, corrosion-resistant fasteners made from a nickel-copper alloy with added aluminum and titanium. This precipitation-hardened material offers excellent mechanical properties, including high tensile strength, superior corrosion resistance, and exceptional performance in marine and chemical environments. Monel K500 bolts retain the corrosion resistance of Monel 400 but with greater hardness and strength due to age hardening. They resist seawater, acidic and alkaline environments, and stress corrosion cracking, making them ideal for offshore, aerospace, and chemical processing applications. These bolts maintain their properties in extreme temperatures, from cryogenic conditions up to around 480°C (900°F). Common types include hex bolts, studs, and socket head cap screws, available in various sizes and specifications. Monel K500 fasteners comply with ASTM B865 and other industry standards. Their durability and strength make them a reliable choice for demanding applications requiring resistance to harsh conditions.
