Product Description
Monel Round Bars (Monel 400 & K500), a premier nickel-copper alloy, is designed to provide exceptional corrosion resistance in aggressive marine and chemical environments, such as seawater, acids, and alkalis. This high-performance alloy is perfect for applications demanding durability and reliability in challenging conditions.
Enhanced by its unique composition, Monel Round Bars, particularly K500, delivers superior yield and tensile strength, with K500 offering nearly three times the strength of Monel 400 through precipitation hardening with aluminum and titanium. Both grades maintain excellent mechanical properties from cryogenic temperatures up to 480°C, ensuring versatility for extreme thermal applications.
The strategic addition of aluminum and titanium in Monel K500 enables age hardening, enhancing strength while preserving outstanding corrosion resistance, while Monel 400 offers excellent ductility and ease of fabrication. These alloys are readily machined and welded in annealed or age-hardened states, serving critical applications in marine engineering, chemical processing, oil and gas production, and high-performance instrumentation.
