UNS N05500, Alloy K-500, W.Nr. 2.4375, Monel® K-500

┃ Overview

UNS N05500 is a precipitation hardenable, nickel-copper alloy, it has low magnetic permeability and strong non-magnetic characteristics over a wide range of temperatures, including subzero. The alloy has similar corrosion resistance to that of Monel 400, with the additional advantage of greater strength and hardness. In addition, 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.

┃ Application

Chemical Processing: Pump and valve components

Marine Service: Chains and cables, fasteners and springs

Oil and Gas: Oil well drill collars and instruments, pump shafts and impellers, non-magnetic housings, safety lifts and valves

Paper Production: Doctor blades and scrapers for pulp processing

Electronic Filed: Sensors and other electronic components


┃Corrosion Resistance

Monel K-500 has similar corrosion resistance to that of Monel 400, except that the alloy has a greater tendency toward stress-corrosion cracking in some environments when in the age-hardened condition. Also, Monel K-500 has been found to be resistant to a sour-gas environment. The combination of very low corrosion rates in highvelocity sea water and high strength make alloy K-500 particularly suitable for shafts of centrifugal pumps in marine service. In stagnant or slow-moving sea water, fouling may occur followed by pitting, but this pitting slows down after a fairly rapid initial attack.


┃Machining

Heavy machining of Monel K-500 is best accomplished when the material is in the annealed condition or hot-worked and quenched condition. Age-hardened material, however, can be finish-machined to close tolerances and fine finishes. The recommended practice, therefore, is to machine slightly oversize, age-harden, then finish to size.


┃Welding

Monel K-500 products may be joined by conventional processes and procedures. Welding alloy K-500 is best accomplished by the gastungsten-arc welding (GTAW) process. MONEL filler metal 60 is normally used. However, the weldments are not age hardenable and, thus, do not have strength matching that of the hardened base metal.
