Hot Rolled & Bright Polished UNS N10276 Nickel Alloy Round Bar Custom Cutting Any Length With Small MOQ
UNS N10276, commonly known as Hastelloy C276, is a premium nickel-molybdenum-chromium alloy renowned for its exceptional corrosion resistance in the harshest industrial environments. Our hot rolled and bright polished UNS N10276 round bars combine robust mechanical performance with precise surface finish, and we offer flexible custom cutting services to meet any length requirement—even for small minimum order quantities (MOQ), making them ideal for both large-scale industrial projects and small-batch precision applications.
1. Chemical Composition of UNS N10276 (Hastelloy C276)
The superior corrosion resistance of UNS N10276 stems from its carefully balanced chemical composition, which minimizes carbide precipitation and enhances resistance to pitting, crevice corrosion, and stress corrosion cracking. The typical composition (by weight) adheres to international standards:
| Element | Content Range (%) | Key Function |
|---|---|---|
| Nickel (Ni) | 57.0 min | Base metal; provides fundamental corrosion resistance and alloy stability |
| Chromium (Cr) | 14.5 - 16.5 | Enhances resistance to oxidizing environments (e.g., acids, high-temperature gases) |
| Molybdenum (Mo) | 15.0 - 17.0 | Boosts resistance to reducing acids (e.g., hydrochloric acid) and pitting |
| Tungsten (W) | 3.0 - 4.5 | Complements molybdenum to improve resistance to localized corrosion |
| Iron (Fe) | 4.0 - 7.0 | Improves mechanical strength and fabricability without compromising corrosion resistance |
| Cobalt (Co) | 2.5 max | Controlled to avoid adverse effects on corrosion performance |
| Carbon (C) | 0.01 max | Low carbon content prevents carbide precipitation during welding/heat treatment |
| Silicon (Si) | 0.08 max | Minimized to reduce oxidation and impurity-related defects |
| Manganese (Mn) | 1.0 max | Aids in alloy processing while maintaining corrosion resistance |
| Phosphorus (P) | 0.04 max | Controlled impurity to avoid brittleness and corrosion weak points |
| Sulfur (S) | 0.03 max | Minimized to prevent hot cracking during fabrication |
2. Mechanical Properties
UNS N10276 round bars exhibit excellent mechanical strength at both room and elevated temperatures, making them suitable for load-bearing applications in harsh environments. The following properties are typical for hot rolled and bright polished bars (annealed condition, room temperature):
| Property | Typical Value | Test Standard |
|---|---|---|
| Tensile Strength | ≥ 795 MPa (115 ksi) | ASTM B574 / ASME SB574 |
| Yield Strength (0.2% offset) | ≥ 310 MPa (45 ksi) | ASTM B574 / ASME SB574 |
| Elongation (in 50 mm) | ≥ 40% | ASTM B574 / ASME SB574 |
| Hardness (Brinell) | ≤ 217 HB | ASTM E10 |
| Hardness (Rockwell B) | ≤ 95 HRB | ASTM E18 |
Note: Mechanical properties can be adjusted via heat treatment (e.g., cold working) for specific high-strength requirements.
3. Standards & Specifications
Our UNS N10276 round bars comply with global industry standards to ensure consistency, quality, and compatibility with international projects. Key standards include:
- 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
UNS N10276 round bars are widely used across industries that demand reliable performance in corrosive or high-temperature environments. Typical applications include:
- 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
Beyond round bars, we offer a full range of UNS N10276 products to support integrated project needs, all adhering to the same high-quality standards:
- 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.
