Monel K-500 Pipe Spool (UNS N05500 / W.Nr. 2.4375)
High-strength corrosion-resistant alloy Pipe Spool for marine pump valve components and chemical processing
As a leading supplier of nickel-based superalloy custom pipe spools, SEATHER TECHNOLOGY specializes in the production of premium Monel K-500 pipe spool (UNS N05500) engineered for exceptional corrosion resistance, high strength, and long-term reliability.
Monel alloy K-500 (UNS N05500 / W.Nr. 2.4375) pipe spool is a nickel-copper alloy which combines the excellent corrosion resistance of Monel 400 pipe spool with the added advantages of greater strength and hardness. The increased properties are obtained by adding aluminum and titanium to the nickel-copper base, and by heating under controlled conditions so that submicroscopic particles of Ni3 (Ti, Al) are precipitated throughout the matrix. The thermal processing used to effect precipitation is commonly called age hardening or aging.
Custom pipe spool fabrication is one of SEATHER’s core manufacturing capabilities. We fabricate complete stainless steel and nickel alloy piping systems—ranging from large industrial projects consisting of thousands of spools to routine maintenance jobs and single-spool orders.
Our production facilities are staffed with highly skilled craftsmen, pipe fitters, welders, and fabricators. Backed by strict quality control, advanced welding processes, and a proven record of safety and precision, we ensure every alloy K-500 pipe spool meets international standards and project-specific requirements. SEATHER is committed to exceeding customer expectations in design accuracy, fabrication quality, delivery schedule, logistics, and cost efficiency.

- Marine engineering applications
- Chemical Industry
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.
