UNS N05500

We are professional UNS N05500 material factory from China

UNS N05500  is a Nickel Copper alloy which combines the excellent corrosion resistance of Alloy 400 with the added advantages of greater strength and hardness. The increase in strength and hardness is a result of the precipitation hardening capability gained by the additions of titanium and aluminum.
We could supply UNS N05500 super alloy in following forms:
Forging:Forged Rings,Forged Pipes,Rolled Rings,Forging Sleeves,Forging Disks,Forged Bushings,Forging Sleeves,Forged Tube Sheets,Forged Shafts,Forged Valve Parts(Valve Bodies,Valve seat rings,valve bonnets) and so on
Sheet,Plate,Strips,Coils
Bar:Round Bars,Square bars,flat bars,hollow bars,hex bars and so on
Pipe & Tube:Seamless tubes,seamless pipes,welded pipes,welded tubes,tubings,coiled tubes,U-bend Tubes.
Fittings (elbows, tees,stub-ends,returns,caps,crosses,reducers,and pipe nipples)
Wire:welded wires,wire rods

The corrosion resistance of UNS N05500 is subtantially equivalent to that of alloy 400 except that, when in the age-hardened condition, UNS N05500 has a greater tendency toward stress-corrosion cracking in some environments. UNS N05500 has been found to be resistant to a sour-gas environment. After 6 days of continuous immersion in saturated (3500ppm) hydrogen sulfide solutions at acidic and basic pH's (ranging from 1.0 to 11.0), U-bend specimens of age-hardened sheet show no cracking. There was some tightly adherent black scale. Hardness of the specimens ranged from 28 to 40 Rc.
The combination of very low corrosion rates in high-velocity sea water and high strength make UNS N05500 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.
UNS N05500 is widely used in following industry
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
