Hastelloy
Hastelloy is a form from Nickel, Chromium, Molybdenum wrought alloy that is the most versatile corrosion resistant alloy and also has excellent resistance to stress corrosion cracking and oxidizing atmosphere up to 1900⁰F
Usage
It is used in pipes and valves in chemical processing and petrochemical industries.
Forms
- Pipes & Tubes.
- Sheets, Plates and Coils.
- Forged and Buttweld Fittings.
- Rods, Bars and Wires.
- Fasteners.
- Ferrous and Non Ferrous.
