Monel K500 Round Bar

Product Detail

Monel® K500 is a nickel-copper alloy with age hardening properties imparted by alloying additions of aluminum and titanium. Its basic composition is similar to that of Monel®400 but the alloying additions make it age hardenable under controlled conditions of temperature and time. This alloy can be delivered in the annealed, stress equalized, hot finished or age-hardened conditions.

Common Applications of 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

Characteristics of Alloy K500:

Excellent corrosion resistance in an extensive range of natural and Chemical environments
Excellent resistance to chloride-ion stress-corrosion cracking
Very high strength and hardness

After age-hardening Monel® K500 alloy has:

Approximately 2 to 3 times higher mechanical properties than Nickel-copper Monel © 400
High tensile properties up to about 650°C (1200°F)
Good fatigue and corrosion fatigue resistance
Low permeability; non-magnetic down to -135°C (-210°F)
