ملخص

A precipitation-hardenable nickel-copper alloy that combines the corrosion resistance of MONEL alloy 400 with greater strength and hardness. It also has low permeability and is nonmagnetic to temperatures as low as -150°F (-101°C). Used for pump shafts, oil-well tools and instruments, doctor blades and scrapers,springs, valve trim, fasteners, and marine propeller shafts.

البنية المجهرية

Monel K-500 which is produced by adding aluminum and titanium to the basic Monel nickel-copper composition also has a face-centered cubic structure. In the agehardened condition a submicroscopic gamma prime Ni3Al phase is

الشخصيات

Monel K-500 has excellent corrosion resistance in an extensive range of natural and chemical environments, excellent resistance to chloride-ion stress-corrosion cracking and very high strength and hardness. After age-hardening, Monel K-500 has approximately 2 to 3 times higher mechanical properties than the nickel-copper alloy (Monel 400), high tensile properties up to about 650 ℃, good corrosion fatigue resistance and ow permeability with non-magnetic down to -135 ℃.

المقاومة للتآكل

In general, the corrosion resistance of Monel K500 is similar to that of Monel 400. Excellent resistance is shown to a wide range of media from pure water to mineral acids, salts and alkalis.
Monel K-500 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. Nicorros Al also shows good resistance in sour-gas environments.

التطبيقات

Monel K-500 finds wide application in the marine, chemical, petrochemical and shipbuilding industries.
Typical applications include:
1. Valve seals, pump sleeves and wear rings in marine
environments – high strength and resistance to seawater;
2. Fasteners, e.g. bolts, used in marine atmospheres and tidal waters – resistance to chloride-containing environments;
3. Doctor blades and scrapers;
4. Towing cable armouring – high strength, non-magnetic properties and resistance to seawater;
5. Oil well drilling equipment such as non-magnetic drill collars, valves and instrumentation sleeves – resistance to chloride-containing media and sour-gas environments;
6.Springs – resistance to a variety of corrosive media;
7.Aviation instrument components – non-magnetic properties.
