Monel K-500 Round Bar Rod (UNS N05500 / W.Nr. 2.4375)
High-strength corrosion-resistant alloy Bar Rod for marine components and chemical processing
As a leading supplier of high-performance nickel alloys, SEATHER TECHNOLOGY manufactures premium-quality Monel K-500 round bar rod (UNS N05500) engineered for outstanding corrosion resistance and mechanical stability.
Monel K-500 is a nickel alloy often used in marine applications. The nickel and copper contents give the alloy excellent room temperature corrosion resistance. At the same time, as a precipitation-strengthened alloy, Monel K-500 can obtain very high strength through aging treatment.
Our K-500 alloy round bars and rods are produced strictly in accordance with ASTM B865, ensuring precise chemical composition, stable mechanical properties, and consistent product quality. Using advanced hot-rolling and cold-drawing processes, we achieve excellent roundness, dimensional accuracy, and uniform microstructure.
To further enhance surface quality and tolerance control, SEATHER offers additional processing options such as centerless grinding, precision polishing, and fine surface finishing. All round bars and rods undergo straightening to ensure compliance with required straightness standards, making them suitable for machining, fabrication, and demanding end-use applications.
With strong technical capability, strict quality control, and competitive pricing, SEATHER TECHNOLOGY delivers reliable Monel K-500 round bar rod (UNS N05500) products that meet the requirements of critical engineering industries.

What is Monel K-500 (UNS N05500)
Alloy K-500 also referred to as the UNS N05500/W.Nr. 2.4375 alloy.
It is a nickel-copper alloy which combines the excellent corrosion resistance of alloy 400 with the added advantages of greater strength and hardness.
K-500 alloy has excellent mechanical properties ranging from sub-zero temperatures up to around 480°C.
Typical applications for alloy K-500 products are chains and cables, fasteners and springs for marine service; pump and valve components for chemical processing; doctor blades and scrapers for pulp processing in paper production; oil well drill collars and instruments, pump shafts and impellers, non-magnetic housings, safety lifts and valves for oil and gas production; and sensors and other electronic components.
