Monel K500 is a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance characteristic
of Monel 400 with the added advantage of greater strength and hardness. These amplified properties, strength and hardness,
are obtained by adding aluminum and titanium to the nickel-copper base and by a thermal processing used to effect
precipitation, typically called age hardening or aging. When in the age-hardened condition, Monel K-500 has a greater
tendency toward stress-corrosion cracking in some environments than Monel 400. Alloy K-500 has approximately three
times the yield strength and double the tensile strength when compared with alloy 400. Plus, it can be further strengthened
by cold working prior to precipitation hardening. The strength of this nickel steel alloy is maintained to 1200° F but stays
ductile and tough down to temperatures of 400° F. Its melting range is 2400-2460° F.
This nickel alloy is spark resistant and non-magnetic to -200° F. However, it is possible to develop a magnetic layer on
the surface of the material during processing. Aluminum and copper may be selectively oxidized during heating, leaving
a magnetic nickel rich film on the outside. Pickling or bright dipping in acid can remove this magnetic film and restore
the non-magnetic properties
Alloy K500 has outstanding corrosion resistance in a variety of environments and is currently employed in marine, oil
and gas and chemical environments. The alloy has excellent mechanical properties ranging from sub-zero temperatures
up to around 480°C. Alloy K500 demonstrates excellent corrosion resistance in many environments including pure
water to non-oxidising mineral acids, salts and alkalis.
