┃ Overview

UNS N06625 is a widely utilized nickel-chromium alloy renowned for its high strength, excellent fabricability, and exceptional corrosion resistance. Strength of Inconel 625 is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix, thus precipitation hardening treatments are not required, this combination of elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization. Service temperatures range from cryogenic to 1800°F (982°C).

┃ Application

Aerospace Field: Aircraft ducting systems, engine exhaust systems, thrust-reverser systems, resistance welded honeycomb structures for housing engine controls, fuel and hydraulic line tubing, spray bars, bellows, turbine shroud rings, and heat-exchanger tubing in environmental control systems.

Sea-water Applications: wire rope for mooring cables, propeller blades for motor patrol gunboats, submarine auxiliary propulsion motors, submarine quick disconnect fittings, exhaust ducts for Navy utility boats, sheathing for undersea communication cables, submarine transducer controls, and steam-line bellows.

Nuclear Field: Reactor-core and control-rod components in nuclear water reactors

Chemical-processing Field: Bubble caps, tubing, reaction vessels, distillation columns, heat exchangers, transfer piping, and valves.


┃Corrosion Resistance

The high alloy content of Inconel 625 enables it to withstand a wide variety of severe corrosive environments. In mild environments such as the atmosphere, fresh water, sea water, neutral salt, and alkaline media, there is almost no attack. In more severe corrosive environments, the presence of nickel and chromium provides the alloy with resistance to oxidizing chemicals, while the combination of nickel and molybdenum provides the alloy with resistance to nonoxidizing environments. In addition, the high molybdenum content also makes this alloy very resistant to pitting and crevice corrosion, and the high nickel content provides freedom from chloride ion stress corrosion cracking. This combination of properties allows Alloy 625 to be used under a wide range of corrosive conditions.


┃ Machining

All standard machining operations are readily performed on Inconel 625. For the best machinability, the alloy should be in the solution-treated condition.


┃Welding

Inconel 625 is best machined in the annealed condition. Low cutting speeds should be used and the cutting tool should be engaged at all times to minimize work-hardening. Adequate cut depth is necessary to assure avoiding contact with the previously formed work-hardened zone.
