Nickel Alloy/High Alloyed Material is known as a series of material with high strength property and anti-corrosion,heat resistant capability under high temperature. It also divided into several series range according to their capability, like Incoloy,Monel,Inconel and Hastelloy.

Inconel Series: INCONEL
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. In age hardening or precipitation strengthening varieties, small amounts of niobium combine with nickel to form the intermetallic compound Ni3Nb or gamma prime (¦Ã¡¯). Gamma prime forms small cubic crystals that inhibit slip and creep effectively at elevated temperatures.
Monel Series:
Monel is primarily composed of nickel(up to 67%) and copper, with some iron and other trace elements.
Compared to steel, Monel is very difficult to machine as it work-hardens very quickly. It needs to be turned and worked at slow speeds and low feed rates. It is resistant to corrosion and acids, and some alloys can withstand a fire in pure oxygen. It is commonly used in applications with highly corrosive conditions. Small additions of aluminium and titanium form an alloy with the same corrosion resistance but with much greater strength due to gamma prime formation on aging.

Hastelloy Series:

Hastelloy is the registered trademark name of Haynes International, Inc. The trademark is applied as the prefix name of a range of twenty two different highly corrosion-resistant metal alloys loosely grouped by themetallurgical industry under the material term ¡°superalloys¡± or ¡°high-performance alloys¡±.
The primary function of the Hastelloy super alloys is that of effective survival under high-temperature, high-stress service in a moderately to severely corrosive, and/or erosion-prone environment where more common and less expensive iron-based alloys would fail, including the pressure vessels of some nuclear reactors, chemical reactors, distillation equipment, and pipes and valves in chemical industry. Electropolishing or passivation of Hastelloy can improve corrosion resistance.
