Its strength as well as its resistance to corrosion and stress make Inconel 625 elbow a suitable component of nuclear reactors, particularly in the control rod and reactor core.
This superalloy is composed mainly of nickel (58% min.) followed by chromium, and molybdenum, niobium, iron, tantalum, cobalt, and trace amounts of manganese, silicon, aluminium, and titanium.
Nuclear systems also generally involve high temperatures beyond 650¡ãC, in which the strength of Inconel 625 elbow can withstand.
Inconel 625 also commonly goes by the names: Haynes 625, Altemp 625, Nickelvac 625, and Nicrofer 6020.
The strength of Inconel 625 lies not only in its nickel-chromium base but also the hardening mechanism of niobium and molybdenum.
The alloy matrix is strengthened by the interaction of niobium with molybdenum that offers high strength without the need for precipitation-hardening treatment.
The tensile strength of this superalloy is 690 MPa, while its yield strength measures 275 MPa.
At high temperatures in the presence of oxidising agents, the titanium and niobium compositions of the oxide film on Inconel 625 increase drastically to form a natural protective layer in the material.
The unique combination of its components makes Inconel 625 highly resistant to corrosive substances.
Superalloy 625 elbow works excellently under high saline seawater, and more so in milder environments such as fresh water and standard atmospheric conditions.
Upon exposure to oxidising agents, Inconel 625 is protected naturally by its nickel-chromium matrix.
Alloy 600 is an superior choice for Nuclear reactor vessels and heat exchanger tubing, Chemical processing equipment, Heat treat furnace components and fixtures, Gas turbine components including jet engines and Electronic parts.
Nickel Alloy 600 is a solid solution of its elements and cannot be strengthened by heat treatment. Cold working will result in increased strength. Heat treatment can remove any undesirable effects of cold work.
