Hastelloy C276 Plate Thickness 3.0 - 50.0mm Hot Rolled and Forged Plate Alloy N10276

1. Core Technical Parameters

2. Key Mechanical & Corrosion Resistance Properties

2.1 Mechanical Properties (at Room Temperature)

2.2 Corrosion Resistance (Core Advantage)

• 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.

4. Product Advantages

1. 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.
2. 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.
3. 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.
4. 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.
5. 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

• 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

• 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.
