Key Features of Hastelloy C276 / Inconel 276 / 2.4819
1. Outstanding Corrosion Resistance
- Excellent resistance to a wide range of aggressive chemicals.
- Performs well in oxidizing and reducing environments.
- Highly resistant to:
Hydrochloric acid, sulfuric acid, and phosphoric acid
Chlorides, hypochlorites, wet chlorine gas
Ferric and cupric chlorides
2. Exceptional Resistance to Localized Corrosion
- Very low tendency for:
Pitting
Crevice corrosion
Stress corrosion cracking (SCC)
3. Strong Mechanical Properties
- Maintains good tensile strength and ductility at both room and elevated temperatures.
- Ideal for high-stress, high-temperature environments.
4. Excellent Fabricability and Weldability
- Can be welded using all standard methods (GTAW, GMAW, SMAW).
- Does not require post-weld heat treatment in most cases.
- Low carbon content minimizes risk of grain boundary carbide precipitation during welding.
5. Heat and Oxidation Resistance
- Good resistance to oxidation at high temperatures, though not typically used above ~1000°C (1830°F) for long-term service.
6. Versatility in Harsh Environments
- Performs reliably in:
Flue gas scrubbers
Seawater and brine systems
Waste treatment
Chemical reactors and mixers
Desulfurization systems
Form-Specific Notes
| Form | Typical Use & Benefit |
|---|---|
| Bar/Rod | Machined into pump shafts, bolts, valve parts – high strength, corrosion-resistant load-bearing components |
| Wire | Welding filler, resistance wire, springs – highly formable, corrosion-resistant |
| Forging | Custom high-strength components, flanges, nozzles – ideal for pressure vessels |
| Plate | Reactor linings, tanks, scrubbers – flat, weldable surfaces with high corrosion protection |
| Strip | Heat exchangers, cladding, gaskets – thin, formable, good for tight spaces |
