Nickel Alloy Monel K500 (UNS N05500) Bright Round Bar
The Monel K-500 alloy has a comparable corrosion resistance of 400, but with higher mechanical strength and hardness. Has good heat corrosion resistance and long-term tissue stability.
MONEL K500 is a nickel-copper alloy, precipitation hardenable through additions of aluminum and titanium. MONEL K500 retains the excellent corrosion resistant characteristics of 400 and has enhanced strength and hardness after precipitation hardening when compared with 400. Alloy K500 has approximately three (3) times the yield strength and double the tensile strength when compared with 400. MONEL K500 can be further strengthened by cold working before the precipitation hardening
The characteristics of Monel K500

Application of Monel K500
Monel K-500 alloy finds wide applications in the marine, chemical, petrochemical and shipbuilding industries. Typical applications include:
Valve seals, pump sleeves and wear rings in marine environments - high strength and resistance to seawater
Pump shafts for fire-fighting pumps - high strength (resulting in smaller diameter shafts) and resistance to flowing seawater
Propeller shafts - high strength (resulting in smaller diameter shafts and thus smaller bearings) and resistance to seawater
Fasteners e.g. bolts, used in marine atmospheres and tidal waters - resistance to chloride - containing environments
Doctor blades and scrapers
Towing cable armoring - high strength, non-magnetic properties and resistance to seawater
Springs - resistance to a variety of corrosive media
Oil well drilling equipment such as non-magnetic drill collars, valves and instrumentation sleeves - resistance to chloride-containing media and sour gas environments
Aviation instrument components - non-magnetic properties
