Description:

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.

Application field

· Sour-gas service applications

· Oil and gas production safety lifts and valves

· Oil-well tools and instruments like drill collars

· Oil well industry

· Doctor blades and scrapers

· Chains, cables, springs, valve trim, fasteners for marine service

· Pump shafts and impellers in marine service

 

Corrosion resistance

The corrosion resistance of alloy K-500 is substantially equivalent to that of alloy 400 except that when in the age-hardened condition, nickel alloy K-500 has a greater tendency toward stress-corrosion cracking in some environments. Monel K-500 has been found to be resistant to a sour-gas environment. The combination of very low corrosion rates in high-velocity sear 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.

 

 

 

Note: If the alloy powder has moisture absorption, or the storage period exceeds 3 months, it should be used before

Carry out drying treatment (150℃, heat preservation for 2 hours)
