Intro: 

Nickel alloy forgings are resistant to oxidation and heat deformation and can withstand very high temperatures, up to 1800 degrees Fahrenheit (982 degrees Celsius). The high chromium content in nickel alloys also helps them retain their shape at high temperatures and to resist corrosion. Nickel alloys used in forging may also include aluminum, iron, and titanium.

Because of its superior resistance to heat, nickel alloys can be among the most difficult to forge, requiring temperatures near the material’s melting point. This aspect limits the applications of nickel forgings to situations in which the properties of nickel are absolutely necessary
