Inconel
Alloys · Uncommon · Modern
A nickel-chromium superalloy designed to operate at temperatures and pressures that destroy conventional metals. Inconel maintains most of its strength at 1000°C, the operating temperature of jet engine turbine blades, while resisting oxidation and corrosion that would reduce steel to scale.

Lore & Narrative
Developed in the 1940s specifically for jet engine turbine blades, which experience pressures and temperatures no previously known material could survive. Without it, modern aviation would not exist. SpaceX uses Inconel in Merlin rocket engine combustion chambers.
