1. Chemical Composition of UNS N10276 (Hastelloy C276)

2. Mechanical Properties

3. Standards & Specifications

• UNS Number: UNS N10276 (official designation for Hastelloy C276 in the U.S. Unified Numbering System)
• ASTM/ASME Standards:
  • ASTM B574 / ASME SB574 (Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloy (UNS N06625) and Nickel-Chromium-Molybdenum-Tungsten Alloy (UNS N10276) Bars and Rods)
  • ASTM B622 / ASME SB622 (Plate, sheet, and strip—relevant for material traceability)
• International Standards:
  • DIN EN 10088-3 (European standard for corrosion-resistant stainless steels and nickel alloys)
  • JIS H4552 (Japanese Industrial Standard for nickel alloy bars)
• Surface Finish:
  • Hot Rolled: Mill finish (slightly rough surface, suitable for preliminary machining)
  • Bright Polished: Ra ≤ 0.8 μm (smooth, reflective surface for applications requiring hygiene or reduced friction)
• Custom Cutting: Any length (from a few centimeters to several meters) with precision cutting tolerance (±0.1 mm) to eliminate waste and reduce on-site processing time.

4. Key Features of UNS N10276 Round Bars

• Exceptional Corrosion Resistance: Resists a wide range of aggressive media, including hydrochloric acid, sulfuric acid, acetic acid, seawater, and chloride-rich environments—outperforming most stainless steels and other nickel alloys.
• High-Temperature Stability: Maintains strength and corrosion resistance at temperatures up to 1093°C (2000°F), making it suitable for high-heat applications (e.g., furnace components, exhaust systems).
• Excellent Fabricability: Easy to machine, weld (with proper procedures to avoid carbide precipitation), and form—even into complex shapes, thanks to its good ductility.
• Low Carbide Precipitation: The low carbon content (≤0.01%) prevents the formation of chromium carbides at grain boundaries, eliminating "sensitization" and ensuring corrosion resistance even after welding or heat treatment.
• Versatile Surface Options: Hot rolled bars for cost-effective machining, and bright polished bars for applications requiring aesthetics, hygiene, or reduced fluid resistance.

5. Applications

• Chemical Processing: Valves, pumps, shafts, and agitators for handling acids (hydrochloric, sulfuric), solvents, and reactive chemicals.
• Oil & Gas: Downhole components, wellhead parts, and pipeline fittings for offshore (seawater exposure) and sour gas (H₂S-rich) environments.
• Pharmaceutical & Food Processing: Mixing shafts, conveyor components, and storage tank internals—complies with hygiene standards and resists cleaning agents.
• Power Generation: Boiler tubes, heat exchanger tubes, and turbine parts for fossil fuel or nuclear power plants (resists high-temperature steam and corrosive byproducts).
• Environmental Engineering: Wastewater treatment equipment, scrubber systems, and flue gas desulfurization (FGD) components—resists acidic and chloride-laden wastewater.
• Aerospace & Defense: Engine components, fuel system parts, and aerospace fasteners—performs in high-temperature, high-stress conditions.

6. Other UNS N10276 (Hastelloy C276) Products

• Sheets & Plates: Available in thicknesses from 0.5 mm to 100 mm, with hot-rolled (HR) or cold-rolled (CR) finishes; ideal for pressure vessels, tanks, and structural components.
• Pipes & Tubes: Seamless and welded tubes/pipes (OD: 6 mm to 600 mm), used in heat exchangers, fluid transport, and offshore pipelines.
• Wire & Wire Mesh: Fine wire (diameter: 0.1 mm to 5 mm) for filters, springs, and electrical components; wire mesh for sieving and separation in corrosive environments.
• Forgings: Custom forgings (e.g., flanges, elbows, valves) for high-pressure, high-stress applications where dimensional precision and strength are critical.
• Fasteners: Bolts, nuts, washers, and studs (various sizes and thread standards, e.g., ISO, ANSI); suitable for securing critical components in corrosive settings.
