Hastelloy C276 Plate Thickness 3.0 - 50.0mm Hot Rolled and Forged Plate Alloy N10276
Hastelloy C276 (Alloy N10276), a premium nickel-molybdenum-chromium alloy, is renowned for its exceptional corrosion resistance and mechanical stability in harsh industrial environments. The hot-rolled and forged plates, with a thickness range of 3.0mm to 50.0mm, are engineered to meet the demanding requirements of high-temperature, corrosive, and pressure-intensive applications. Below is a detailed overview of its parameters, properties, standards, advantages, applications, and related products.
1. Core Technical Parameters
The 3.0 - 50.0mm hot-rolled and forged Hastelloy C276 plates adhere to strict material and dimensional specifications, ensuring consistency and reliability in end-use.

| Thickness Range | 3.0mm - 50.0mm (custom thicknesses available for special orders) |
| Plate Width | 1000mm - 2500mm (standard); up to 3000mm (forged, based on forging capacity) |
| Plate Length | 2000mm - 6000mm (standard); customizable for large-scale projects |
| Processing Method | Hot rolling (for uniform thickness, good surface finish) + Forging (for enhanced density, reduced internal defects) |
| Chemical Composition | Nickel (Ni): ≥ 57%, Molybdenum (Mo): 15.0 - 17.0%, Chromium (Cr): 14.5 - 16.5%, Tungsten (W): 3.0 - 4.5%, Iron (Fe): ≤ 5.0%, Cobalt (Co): ≤ 2.5%, Carbon (C): ≤ 0.01%, Silicon (Si): ≤ 0.08%, Manganese (Mn): ≤ 1.0% |
| Density | 8.89 g/cm³ |
| Melting Point | 1325 - 1370°C (2417 - 2500°F) |
2. Key Mechanical & Corrosion Resistance Properties
Hastelloy C276 plates excel in both mechanical performance and corrosion resistance, making them suitable for extreme operating conditions.
2.1 Mechanical Properties (at Room Temperature)
| Property | Hot-Rolled Plate (3.0 - 50.0mm) | Forged Plate (3.0 - 50.0mm) |
|---|---|---|
| Tensile Strength (σb) | ≥ 690 MPa | ≥ 720 MPa |
| Yield Strength (σ0.2) | ≥ 310 MPa | ≥ 330 MPa |
| Elongation (δ) | ≥ 40% | ≥ 35% |
| Hardness (HB) | ≤ 210 | ≤ 230 |
2.2 Corrosion Resistance (Core Advantage)
Hastelloy C276 is widely recognized as one of the most corrosion-resistant alloys, primarily due to its high molybdenum and chromium content, which forms a dense, stable oxide film on the surface. Its key corrosion-resistant features include:
- Resistance to Reductive Acids: Unaffected by dilute sulfuric acid, hydrochloric acid, and phosphoric acid (even at moderate temperatures and concentrations).
- Resistance to Oxidative Environments: Withstands nitric acid, chromic acid, and hypochlorite solutions (common in chemical cleaning processes).
- Pitting & Crevice Corrosion Resistance: Performs exceptionally well in chloride-rich environments (e.g., seawater, brine) without pitting or crevice damage (critical for marine and offshore applications).
- High-Temperature Stability: Maintains corrosion resistance and mechanical strength at temperatures up to 1093°C (2000°F), with no significant oxidation or carbide precipitation.
3. Compliance Standards
To ensure quality and compatibility with global industrial practices, the 3.0 - 50.0mm Hastelloy C276 hot-rolled and forged plates comply with the following international standards:
| Standard Organization | Standard Number & Title |
|---|---|
| ASTM (USA) | ASTM B575 - Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloy Plate, Sheet, and Strip (Alloy C276) |
| ASME (USA) | ASME SB575 - Boiler and Pressure Vessel Code (BPVC) Approved Material (for pressure vessels) |
| DIN (Germany) | DIN EN 10088-1 - Stainless Steels and Heat-Resisting Steels (includes Alloy N10276) |
| JIS (Japan) | JIS H4552 - Nickel Alloys for Pressure Vessels and Piping (equivalent to Hastelloy C276) |
| ISO (International) | ISO 6208 - Nickel and Nickel Alloys - Plate, Sheet and Strip (covers Alloy N10276) |
4. Product Advantages
Compared to other nickel alloys or stainless steels, the 3.0 - 50.0mm Hastelloy C276 hot-rolled and forged plates offer unique benefits:
- Superior Corrosion Resistance: Outperforms 316L stainless steel and even other Hastelloy grades (e.g., C22) in mixed acid or chloride-rich environments, reducing maintenance costs and downtime.
- Enhanced Ductility & Formability: Hot rolling and forging improve the alloy’s ductility, allowing the plates to be bent, welded, or machined into complex shapes (e.g., pressure vessel shells, heat exchanger tubesheets) without cracking.
- High-Temperature Durability: Maintains tensile strength and corrosion resistance at elevated temperatures (up to 1093°C), making it ideal for high-heat applications like incinerators or chemical reactors.
- Dimensional Precision: The 3.0 - 50.0mm thickness range is strictly controlled (tolerance: ±0.1mm for thin plates, ±0.3mm for thick plates), ensuring a perfect fit in assembly.
- Low Carbon Content: With C ≤ 0.01%, the alloy avoids carbide precipitation at grain boundaries (a common cause of intergranular corrosion), even after long-term exposure to high temperatures.
5. Typical Applications
The 3.0 - 50.0mm Hastelloy C276 hot-rolled and forged plates are widely used across industries that demand corrosion resistance and high-temperature stability:
- Chemical Processing: Reactors, pressure vessels, and storage tanks for handling acids (sulfuric, hydrochloric), solvents, and chemical intermediates.
- Oil & Gas: Downhole tubular components, wellhead equipment, and offshore platform structures (resistant to seawater corrosion and sour gas/hydrogen sulfide).
- Pharmaceutical & Food Processing: Equipment for sterile production (e.g., blending tanks, heat exchangers) – the alloy is non-toxic and easy to clean, complying with FDA standards.
- Waste Incineration: Furnace liners and flue gas ducts (resistant to high temperatures and corrosive ash/acidic gases).
- Marine Engineering: Ship hulls, propeller shafts, and offshore wind turbine foundations (withstands seawater and salt spray corrosion).
- Power Generation: Heat exchanger tubes and boiler components in coal-fired or nuclear power plants (resistant to high-temperature steam and corrosive byproducts).
6. Other Hastelloy C276 Products
Beyond 3.0 - 50.0mm hot-rolled and forged plates, Hastelloy C276 is available in various forms to meet diverse application needs:
- Sheets & Strips: Thickness 0.1mm - 3.0mm, width 100mm - 2000mm; used for thin-walled components (e.g., heat exchanger fins, electronic enclosures).
- Pipes & Tubes: OD 6mm - 630mm, wall thickness 0.5mm - 20mm; applied in chemical transport pipelines and oilfield tubulars.
- Bars & Rods: Diameter 5mm - 300mm; used for machined parts (e.g., valves, fasteners, pump shafts).
- Welding Consumables: Wires (diameter 0.8mm - 3.2mm) and electrodes; designed to match the corrosion resistance of C276 plates/pipes, ensuring strong, corrosion-resistant weld joints.
- Forgings: Custom-shaped forgings (e.g., flanges, elbows, pressure vessel heads); manufactured via open-die or closed-die forging for heavy-duty applications.
