| Thickness Range | Sheets: 0.1 mm – 6.0 mm; Plates: 6.0 mm – 100.0 mm (custom thicknesses available upon request) |
| Laser Cutting Capabilities | - Cut size: Any custom size (from small precision components to large plates)
- Cutting tolerance: ±0.1 mm (high precision for tight-fit applications)
- Edge quality: Burr-free, smooth edges (eliminates post-processing needs)
- Cut shapes: Complex geometries (holes, notches, irregular patterns) supported by CAD design |
| Surface Finish | Standard: Hot-rolled (HR) with mill finish; Optional: Cold-rolled (CR) for smoother surface, polished finish (for hygiene-critical applications) |
2. Mechanical & Corrosion Performance
Hastelloy C276’s performance is defined by its robust mechanical strength and unmatched resistance to aggressive media—key reasons it is favored in extreme conditions.
Mechanical Properties (Annealed Condition)
| Property | Value (Typical) |
| Tensile Strength | ≥ 720 MPa |
| Yield Strength (0.2% Offset) | ≥ 310 MPa |
| Elongation (in 50 mm) | ≥ 40% |
| Hardness (Brinell) | ≤ 210 HB |
Corrosion Resistance (Key Advantage)
- Resists uniform corrosion: Excellent performance in sulfuric acid, hydrochloric acid, phosphoric acid, and organic acids (e.g., acetic acid, formic acid).
- Chloride stress corrosion cracking (SCC) resistance: Unaffected by chloride-rich environments (e.g., seawater, brines, chemical process streams), a critical advantage over many stainless steels.
- Pitting & crevice corrosion resistance: Maintains integrity in stagnant or low-flow conditions where localized corrosion often occurs.
- Oxidation resistance: Stable up to 1093°C (2000°F) in air, with minimal scaling or degradation.
3. Manufacturing & Quality Standards
Hastelloy C276 sheets and plates comply with global industry standards to ensure quality, traceability, and compatibility with engineering codes:
- Primary Standard: ASTM B575 (Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloy (UNS N10276) Plate, Sheet, and Strip) – the most widely recognized standard for this alloy in North America and global markets.
- Additional Standards:
- ASME SB575 (for pressure vessel and boiler applications, adhering to ASME Boiler and Pressure Vessel Code).
- DIN EN 10088-1 (European standard, aligning with Alloy 2.4819 designation).
- ISO 6208 (International Organization for Standardization, covering nickel alloy plates/sheets for general industrial use).
4. Specifications (Size & Form)
Beyond custom laser-cut dimensions, standard and configurable specifications include:
- Width: 1000 mm – 2500 mm (standard); custom widths up to 3000 mm available.
- Length: 2000 mm – 6000 mm (standard); cut-to-length or coil form (for thin sheets, 0.1–3.0 mm) supported.
- Tolerance: Complies with ASTM B575 Class A (tight dimensional tolerance) for critical applications; Class B available for non-precision uses.
5. Equivalent Grades (Same Alloy, Different Designations)
Hastelloy C276 is known by various global 牌号 (grades) across regions, ensuring consistency in material performance:
| Region/Standard | Grade Designation | UNS Number |
| North America | Hastelloy C276 | N10276 |
| Europe | Alloy 2.4819 | N10276 |
| Germany (DIN) | W.Nr. 2.4819 | N10276 |
| France (AFNOR) | NC17D | N10276 |
| Japan (JIS) | NW276 | N10276 |
| China (GB) | NS334 | N10276 |
6. Key Applications
Leveraging its corrosion resistance and customizability, Hastelloy C276 sheets/plates are used in industries requiring long-term reliability in harsh conditions:
- Chemical Processing: Reactors, heat exchangers, separators, and piping components for handling acids (sulfuric, hydrochloric) and corrosive intermediates.
- Oil & Gas: Downhole tubulars, wellhead components, and offshore platform parts (resistant to seawater and sour gas).
- Pharmaceutical & Food Processing: Tanks, mixers, and conveyor systems (complies with hygiene standards and resists organic acids/cleaning agents).
- Environmental Engineering: Flue gas desulfurization (FGD) systems, wastewater treatment equipment (resists acidic scrubber solutions).
- Aerospace & Defense: Engine components and fuel systems (withstands high temperatures and aggressive fuels).
- Power Generation: Boiler tubes, heat recovery steam generators (HRSGs) in coal-fired or waste-to-energy plants.
7. Other Hastelloy C276 Product Types
In addition to sheets and plates, Hastelloy C276 is available in a full range of forms to support end-to-end system integration:
- Pipes & Tubes: Seamless and welded tubes (per ASTM B622/B751) for fluid transport in corrosive systems.
- Fittings: Elbows, tees, reducers, and flanges (per ASTM B366) – compatible with C276 pipes/tubes.
