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.
