1. What Is Hastelloy C276?
Hastelloy C276 is a nickel-based alloy developed for demanding environments where corrosion resistance and material reliability are important. It contains nickel, chromium, molybdenum and tungsten, which contribute to its performance in a wide range of aggressive chemical environments.
The material is also identified by UNS N10276 and commonly referred to as Alloy C-276. It is used in chemical processing equipment, reactors, heat exchangers and other industrial components exposed to corrosive process conditions.
For engineers, procurement teams and industrial buyers, understanding Hastelloy C276 properties helps determine whether the alloy is suitable for the intended operating environment.
2. Hastelloy C276 Equivalent Designations
When searching for Hastelloy C276, buyers may encounter several material identifiers across technical documents and supplier listings.
| Designation | Description |
|---|---|
| Hastelloy C-276 | Common alloy name |
| Alloy C-276 | Alternative commercial reference |
| UNS N10276 | Unified Numbering System designation |
| ASTM B574 | Specification commonly associated with nickel-alloy bars and rods, including applicable C-276 products |

Important: Always confirm the product form, governing specification, material condition and required documentation. Similar-looking designations do not automatically mean that every product or supply condition is interchangeable.
For an authoritative overview, refer to the HASTELLOY C-276 alloy technical datasheet from Haynes International.
3. Hastelloy C276 Chemical Composition
The alloy’s chemical composition is central to its performance in demanding industrial service. The following table gives nominal or maximum values from the manufacturer’s technical information; it is not a substitute for the applicable product specification or material test certificate.
| Element | Typical published composition |
|---|---|
| Nickel | Balance, approximately 57% |
| Chromium | Approximately 16% |
| Molybdenum | Approximately 16% |
| Tungsten | Approximately 4% |
| Iron | Approximately 5% |
| Cobalt | 2.5% maximum |
| Manganese | 1% maximum |
| Vanadium | 0.35% maximum |
| Silicon | 0.08% maximum |
| Carbon | 0.01% maximum |
Actual limits and reported values should be checked against the governing standard and the material certificate supplied with the specific order.
4. Key Hastelloy C276 Properties
Corrosion resistance
Hastelloy C276 is known for resistance to many reducing and oxidizing chemical environments. Its high chromium and molybdenum content helps provide resistance to pitting and crevice corrosion in chloride-containing conditions.
Suitability depends on the chemical concentration, temperature, impurities, flow conditions and other process variables. The alloy should not be selected solely from a general corrosion-resistance claim.
Resistance to chloride-related attack
Chloride-bearing environments can cause serious corrosion problems in many industrial materials. C276 is used in selected applications where pitting, crevice corrosion or stress-corrosion cracking are concerns.
Fabrication and welding
The alloy can be formed and welded using suitable procedures. Fabrication requirements should be reviewed by qualified personnel, especially for equipment exposed to aggressive chemicals or critical operating conditions.
Performance in chemical-processing environments
Hastelloy C276 is used in process equipment handling a variety of corrosive chemicals. Final material selection should be based on the actual service conditions and appropriate engineering review.
5. Hastelloy C276 Technical Specifications
| Parameter | Information |
|---|---|
| Material family | Nickel-based corrosion-resistant alloy |
| Common designation | Hastelloy C276 / Alloy C-276 |

Specifications and available forms vary by product. Confirm the required dimensions, tolerances, condition and documentation before placing an order.
6. Industrial Applications of Hastelloy C276
Hastelloy C276 is considered for equipment where the process environment places demanding requirements on material corrosion performance.
Chemical processing: Selected reactors, process vessels, piping components and equipment handling aggressive chemicals.
Heat exchangers: Components exposed to corrosive process fluids, subject to temperature and chemical compatibility checks.
Pollution control: Selected scrubber and flue-gas treatment equipment where corrosion is a major design concern.
Petrochemical processing: Components used in particular process streams that require carefully evaluated corrosion resistance.
Pulp and paper processing: Equipment exposed to corrosive chemicals in selected manufacturing stages.
Industrial process equipment: Specialised components where operating conditions justify the use of a nickel-based corrosion-resistant alloy.
The correct grade must be selected using actual service conditions, not industry name alone.
7. What to Check Before Purchasing Hastelloy C276
Before requesting a quotation, prepare the following details:
- Product form: Round bar, rod or another required form.
- Dimensions: Diameter, thickness, width and length.
- Specification: Applicable ASTM, ASME or project-specific requirement.
- Material condition: Specify the required condition where relevant.
- Documentation: Confirm whether a material test certificate or third-party inspection is required.
- Quantity: State the number of pieces or required weight.
- Delivery location: Provide the destination for freight and delivery planning.
Complete specifications help suppliers respond more accurately and reduce the risk of ordering a material that does not meet the application requirements.
