Superalloy HastelloyX is a nickel-chromium-molybdenum alloy with the addition of cobalt and tungsten.
HastelloyX alloys have excellent oxidation resistance at high temperatures up to 1200°C and can also be used in neutral and reducing atmospheres.
At the same time, HastelloyX alloys are resistant to carbonizing and nitriding atmospheres.
HastelloyX has the following properties
Excellent oxidation resistance up to 1200ºC
High temperature strength is good
Good formability and weldability
Good resistance to stress corrosion cracking
HastelloyX application areas
HastelloyX is widely used in various high temperature environments due to its corrosion resistance in various atmospheres at high temperatures and its excellent high temperature strength.
Typical application areas:
Industrial and aviation steam turbines (combustors, rectifiers, structural covers)
Industrial furnace components, support rolls, grids, ribbons and radiant tubes
Spiral tubes in petrochemical furnaces
High temperature gas cooling nuclear reactor
