DESCRIPTION
Inconel Alloys or are highly engineered to offer a superior combination of high temperature corrosion resistance, toughness , heat resistance and strength and for the most demanding applications.Inconel is a family of austenite nickel-chromium-based superalloys. The name is a trademark of Special Metals Corporation, a wholly owned subsidiary of Precision Castparts Corp. Inconel alloys are oxidation and corrosion resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy.• INCONEL® alloy 625• INCONEL® alloy 601• INCONEL® alloy 601GC®• INCONEL® alloy 603XL• INCONEL® alloy 617• INCONEL® alloy 600• INCONEL® alloy 625LCF®• INCONEL® alloy 686• INCONEL® alloy 690• INCONEL® alloy 693•INCONEL® alloy 706•INCONEL® alloy 718In what forms ?Sheet / plates / coilPipes / tubesBar / wiresFlat / channelFittingsFlangesfastnersTRANSCRIPT

Nickel and Nickel Alloys
These groups of alloys are used for their outstanding corrosion and high temperature resistance. Many are metallurgic ally related to the austenitic stainless steels but are much more highly alloyed, particularly with nickel, chromium and molybdenum in order to enhance their corrosion resistance. These alloys are used resist extremely corrosive conditions in the energy, power, chemical and petrochemical industries.
The term “super alloy” is applied to alloys which have outstanding high temperature strength and oxidation resistance. The nickel-based super alloys contain carefully balanced alloying additions of chromium, cobalt, aluminum, titanium and other elements. Often components are produced by carefully controlled solidification in order to get an optimum directionally solidified or even single crystal structure. These components can have strengths at 1000°C which exceed that of ordinary steels at room temperature. They are essential in the hottest parts of gas turbines both for power generation and aircraft.
These nickel chromium base alloys are used extensively in applications where heat resistance and/or corrosion resistance is required. In some members of the group, where conditions are less demanding, some nickel is replaced by iron to decrease the overall cost.
Metals fail at high temperatures by both oxidation (scaling) and through a loss in strength. Alloys in this class are designed to resist failure from both of these mechanisms. Nickel alloys are not suitable for high temperature sulphur rich environments.
Where corrosion resistance is significant, molybdenum is used as an alloying addition in nickel chromium based alloys.

This group of alloys are frequently sold under trade name specifications but most are listed in the Unified Numbering System. Common trade names are
HASTELLOY, INCOLOY, INCONEL, NICROFER, NICROM and NIMONIC.
The more recent nickel chromium base alloys in these groups also have a wide range of ancillary elements added to give special properties - some of these can be quite complicated and require very close control over composition and heat treatment

This list is far from exhaustive and enquiries to nickel alloy manufacturers’ should be made for specialized high temperature or corrosive situations.
All metals 'creep' under stress at high temperature and in their manufactured form, components may deform. This deformation could cause failure. Nickel alloys have higher strength and longer life at elevated temperature than most alloys. This makes them ideal for such parts as blades and disks in gas turbine engines. The designer however, must determine the expected life of each component and use the appropriate creep and rupture strength in the design.

A number of other applications for nickel alloys involve the unique physical properties of special-purpose nickel-base or high-nickel alloys. These include:
Low-expansion alloys
Electrical resistance alloys
Soft magnetic alloys
Shape memory alloys
Heat-Resistant Applications. Nickel-base alloys are used in many applications where they are subjected to harsh environments at high temperatures. Nickel-chromium alloys or alloys that contain more than about 15% Cr are used to provide both oxidation and carburization resistance at temperatures exceeding 760°C.
Corrosion Resistance. Nickel-base alloys offer excellent corrosion resistance to a wide range of corrosive media. However, as with all types of corrosion, many factors influence the rate of attack. The corrosive media itself is the most important factor governing corrosion of a particular metal.
Low-Expansion Alloys. Nickel was found to have a profound effect on the thermal expansion of iron. Alloys can be designed to have a very low thermal expansion or display uniform and predictable expansion over certain temperature ranges.
Iron-36% Ni alloy (Invar) has the lowest expansion of the Fe-Ni alloys and maintains nearly constant dimensions during normal variations in atmospheric temperature.
The addition of cobalt to the nickel-iron matrix produces alloys with a low coefficient of expansion, a constant modulus of elasticity, and high strength.
Electrical Resistance Alloys. Several alloy systems based on nickel or containing high nickel contents are used in instruments and control equipment to measure and regulate electrical characteristics (resistance alloys) or are used in furnaces and appliances to generate heat (heating alloys).
Types of resistance alloys containing nickel include:

Cu-Ni alloys containing 2 to 45% Ni
Ni-Cr-Al alloys containing 35 to 95% Ni
Ni-Cr-Fe alloys containing 35 to 60% Ni
Ni-Cr-Si alloys containing 70 to 80% Ni
Types of resistance heating alloys con-training nickel include:
Ni-Cr alloys containing 65 to 80% Ni with 1.5% Si
Ni-Cr-Fe alloys containing 35 to 70% Ni with 1.5% Si + l% Nb
Soft Magnetic Alloys. Two broad classes of magnetically soft materials have been developed in the Fe-Ni system. The high-nickel alloys (about 79% Ni with 4 to 5% Mo; bal Fe) have high initial permeability and low saturation induction.
Shape Memory Alloys. Metallic materials that demonstrate the ability to return to their previously defined shape when subjected to the appropriate heating schedule are referred to as shape memory alloys. Nickel-titanium alloys (50Ni-50Ti) are one of the few commercially important shape memory alloys.
Commercial Nickel and Nickel Alloys
The commercial forms of nickel and nickel-base alloys are fully austenitic and are used/selected mainly for their resistance to high temperature and aqueous corrosion.
Commercially Pure and Low-Alloy Nickels. Nickel is supplied to the producers of nickel alloys in powder, pellets, or anode forms. This has led to a whole series ofalloy modifications, with controlled compositions having nickel contents ranging from about 94% to virtually 100%.
These materials are characterized by high density, offering magnetic and electronic property capabilities. They also offer excellent corrosion resistance to reducing environments, along with reasonable thermal transfer characteristics. Some nickels of commercial importance include: Nickel 200, Nickel 201, Nickel 205, Nickel 270 and 290, Permanickel Alloy 300, Duranickel Alloy 301.
Nickel-copper alloys have been found to possess excellent corrosion resistance in reducing chemical environments and in sea water, where they deliver excellent service in nuclear submarines and various surface vessels. By changing the various proportions of nickel and

Soft Magnetic Alloys. The nickel-iron alloys also offer an interesting set of magnetic permeability properties, which have played an important part in switchgear and for direct current (dc) motor and generator designs.
Welding Alloys. Welding products for nickel alloys have similar compositions to the base metals, although additions of aluminum, titanium, magnesium, and other elements are made to the filler metals and welding electrodes to ensure proper deoxidation of the molten weld pool and to over-come any hot-short cracking and malleability problems.
