Inconel 625 is a high-performance alloy of nickel-chromium-molybdenum noted for its high strength rating, resistance to temperature and resistance to corrosion. This superalloy consists primarily of nickel, followed by chromium, molybdenum, niobium, iron, tantalum, cobalt, and trace quantities of manganese, silicon, aluminium, and titanium (58% min.).
What are the applications of Inconel 625?
Marine applications
Inconel 625 is suitable for high saline, underwater applications due to its high corrosion resistance — in particular pitting and crevice resistance. The Inconel alloy 625 is used as propeller blades for warships, mooring lines for securing ships, submarine accessories and fixtures, and oceanographic equipment components.
Nuclear technology
The strength as well as its corrosion and stress resistance make Inconel 625, especially in the control rod and reactor core, a suitable component of nuclear reactors.
Aerospace Industry
Inconel 625 is particularly used for exhaust equipment, fuel lines, heat exchanger casings, and rocket components, have also found their way into the aircraft industry. This is because, even in severe temperatures under high stress, Inconel 625 performs well.
Inside aerospace, there are many possible applications for this technical alloy, including aircraft ducting systems and jet engines. Thanks to its flexibility, the actual list of applications is quite lengthy. Thanks to its high-temperature resistance, magnetic properties and corrosion resistance, nickel alloys are chosen around the board. They are also some of the hardest materials available commercially.
Industrial processing
It is a valuable component in the manufacture of manufacturing equipment such as vessels, heat exchangers, valves, and fluid delivery systems since the alloy is easily manufacturable and resistant to heat and corrosion.
This is definitely not the end for the use of Inconel alloy 625. Owing to the high resistance of the material to potable and salted water, it is also used in pipelines for the collection of sour gas. The pipelines themselves may either be designed using Inconel alloy 625, or clad in the alloy for a more economical option.
The alloy can be used in heat exchangers for seawater, power plants and top-side offshore services. It is also used for other applications of sea water, such as mooring cables, boat propeller blades, propulsion engines, submarine transducer controls and fittings, and utility boat exhaust ducts. It also has the ability for use in submerged control components, electrical cable connectors and oceanographic instrument components.
