Applications & Benefits
Why this grade
Hastelloy C276 carries roughly 16% chromium, 16% molybdenum and 4% tungsten, and it is the general-purpose member of the C family: it holds up in oxidising and reducing media alike, in wet chlorine, hypochlorite, seawater and flue-gas desulphurisation. It is the default C grade — move to C22 or C2000 only where a specific environment defeats it.
- Chemical reactors, piping, and vessels handling oxidizing and reducing acids
- Oil & gas processing, sour environment piping, and subsea equipment
- Marine seawater systems, desalination plants, and heat exchangers
- Pharmaceutical equipment requiring corrosion resistance in complex chemical media
- Power plant pollution control and heat recovery systems
