Neeka Tubes exporter and supplier of Inconel alloysC- 276, HX, 22, 600, 601, 625&718in the form of Plate, Sheet, Bar, Wire, Pipe, Tubing, Pipe Fittings, Flanges and Electrode.
The registered trademark name, Inconel, is applied as the prefix name to more than twenty different highly corrosion resistant high temperature strength metal alloys produced by Special Metals Corporation. These Inconel alloys orsuperalloysare nickel-based alloys that exhibit traits such as high resistance to corrosion, oxidation, carburization, pitting, crevice, corrosion cracking, and high temperature strength. Often, Inconel is referred to as Inco.
Alloys of identical chemical and mechanical properties are available from other manufacturers and offerexcellent alternatives to the various Inconel brand alloys.
The corrosion-resistant superalloys are widely used in extreme environments where tremendous heat and corrosion resistance is paramount to the integrity of the end product. Chemical processing, nuclear, petrochemical, aerospace and marine industries widely use these superalloys.

In what Applications are Inconel alloys used?
Inconel 600 is a nickel-chromium alloy used for applications that require corrosion and high temperature resistance. This nickel alloy was designed for service temperatures from cryogenic to elevated temperatures in the range of 2000 F. It is non-magnetic, has excellent mechanical properties, and presents the desirable combination of high strength and good weldability under a wide range of temperatures. The high nickel content in Inconel 600 enables it to retain considerable resistance under reducing conditions, makes it resistant to corrosion by a number of organic and inorganic compounds, gives it excellent resistance to chloride-ion stress-corrosion cracking and also provides excellent resistance to alkaline solutions. Typical applications of this nickel alloy include the chemical, pulp and paper, aerospace, nuclear engineering and heat treating industries.

In what applications is Inconel 600 used?
Fabrication with Inconel 600
Alloy 600 can be both hot formed and cold formed using typical processes. Hot working should be performed between 1600 F and 2250 F avoiding any work between1200-1600 F because the ductility decreases in this temperature range. Welding Alloy 600 can be achieved via shielded metal-arc welding, TIG, and MIG.

Cupronickel (also referred to as "cupernickel" or copper-nickel alloy) refers to a group of copper-nickel alloys that are used in saltwater environments due to their corrosion resistant properties.
The most common cupronickel alloys are:These alloys have good working properties, are readily weldable and considered insensitive to stress corrosion. Cupronickel is also resistant to biofouling, crevice corrosion, stress corrosion cracking and hydrogen embrittlement.
Slight differences in corrosion resistance and strength generally determine which alloy grade is used for a particular application
Corrosion Resistance:Cupronickel resists corrosion in seawater because its electrode potential is essentially neutral in such environments.
Consequently, it will not form electrolytic cells when placed in close proximity to other metals within an electrolyte, which is the main cause of galvanic corrosion.
Copper also naturally forms a protective oxide layer on its surface when exposed to seawater, which protects the metal from deterioration.
Applications:Cupronickel is used in:
