2.4662 – Alloy 901 is a nickel-based superalloy that possesses high strength levels and resistance to elevated temperatures. It is commonly produced by VIM + CER, VIM+VAR or VIM+ESR methods to achieve high levels of metallurgical purity and the desired creep-life & stress-rupture properties under elevated temperatures.
Alloy 901 is an alloy typically used under elevated temperatures, typically up to 600 degrees Celsius. Common applications are gas turbines, pressure vessels, petrochemical applications etc. Alloy 901 is forged in three-stage process by first applying a solution annealing heat treatment, and afterwards two rounds of ageing and stabilization / precipitation. Moreover, this alloy has great corrosion resistance properties and can successfully be machined in all conditions. It does not observe great welding characteristics and as such any welding should preferably be performed on the material in the solution annealed condition. Appropriate heat treatment is recommended post-welding.
