Applications & Benefits
Why this grade
Hastelloy C2000 combines the high molybdenum of C276 with the high chromium of C22 and adds about 1.6% copper. It is specified where one alloy has to cope with both oxidising and reducing conditions — process swings, upset conditions, or mixed acid streams — rather than changing material partway through a plant.
- Chemical: Mixed-acid systems, oxidizing/reducing environments, process vessels, heat exchangers.
- Marine: Offshore piping, scrubbers, seawater cooling systems.
- Oil & Gas: Sour gas lines, downhole components, subsea equipment.
- Pharma: Reactor internals, sterile process equipment.
- Power: Turbo machinery, furnace parts, flue gas scrubbers, heat exchangers.
- Hardware and OEM: Precision stock, urgent repair parts, long-term corrosion resistance projects.
