Inconel
Inconnel alloys are oxidation and corrosion resistant materials which are well suited for usage in extreme environments subjected to pressure and heat.
Usage
Inconel is used in Gas turbine blades, seals, electric submersible well pump motor shafts, Chemical processing and pressure vessel.
Forms
- Pipes & Tubes.
- Sheets, Plates and Coils.
- Forged and Buttweld Fittings.
- Rods, Bars and Wires.
- Fasteners.
- Ferrous and Non Ferrous.
