ALLOYK500 (Monel K500)
ALLOYK500 is a Ni-Cu alloy with age-hardening properties imparted by alloying additions of aluminium and titanium. Its basic composition is similar to that of ALLOY400 but the alloying additions make it age hardenable under
controlled conditions of temperature and time.
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
After age-hardening of characeristics of ALLOY K500
- approximately 2 to 3 times higher mechanical properties than the ALLOY400>
- 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)

In general, the corrosion resistance of Alloy K500 is similar to that of ALLOY400. Excellent resistance is shown to a wide range of media from pure water to mineral acids, salts and alkalis. Alloy K500 is virtually immune to chloride-ion stress-corrosion cracking. In the aged condition, the alloy may be susceptible to stress-corrosion cracking in moist, aerated hydrofluoric acid vapour at stresses near the yield strength. In high-velocity seawater and in marine atmospheres, good corrosion resistance is shown but, in slow-moving or stagnant seawater, pitting may occur. Alloy K500 also shows good resistance in sour-gas environments.
ALLOYK500 finds wide application in the marine, chemical, petrochemical and shipbuilding industries.
Typical applications are:
- 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
- fasteners, e.g. bolts, used in marine atmospheres and tidal
waters - resistance to chloride-containing environments
- doctor blades and scrapers
- towing cable armouring - 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
