ASTM B574 Hastelloy C276 Nickel Alloy Round Bar Diameter 6 - 340mm Black Bar Bright Bar

Hastelloy C276 nickel alloy round bar, manufactured in strict compliance with ASTM B574 standard, is a premium corrosion-resistant material widely used in harsh industrial environments. Available in diameter ranges from 6mm to 340mm, it offers two surface finishes—black bar (hot-rolled, with a rough, oxide-rich surface for cost-effectiveness and subsequent machining) and bright bar (cold-finished, featuring a smooth, polished surface for applications requiring tight dimensional tolerance and aesthetic appeal). Below is a detailed overview of its key attributes, related grades, processing services, and logistics solutions.

1. Chemical Composition

Hastelloy C276’s exceptional corrosion resistance stems from its precisely balanced chemical composition, which inhibits carbide precipitation and enhances resistance to pitting, crevice corrosion, and stress corrosion cracking. The typical composition (by weight) meets ASTM B574 requirements as follows:

 

Element Content Range (%) Key Function
Nickel (Ni) 54.0 - 60.0 Base element; 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 non-oxidizing acids (e.g., hydrochloric acid) and pitting
Tungsten (W) 3.0 - 4.5 Complements molybdenum to improve crevice corrosion resistance in chloride-rich media
Iron (Fe) 4.0 - 7.0 Improves alloy workability and reduces cost without compromising performance
Cobalt (Co) ≤ 2.5 Controlled to minimize potential embrittlement in high-temperature services
Carbon (C) ≤ 0.010 Low carbon content prevents carbide precipitation during welding/heat treatment
Silicon (Si) ≤ 0.08 Reduces oxide formation and improves casting/machining quality
Manganese (Mn) ≤ 1.0 Enhances hot workability and ductility
Phosphorus (P) ≤ 0.040 Controlled to avoid brittleness and corrosion defects
Sulfur (S) ≤ 0.030 Minimized to prevent intergranular corrosion and machining burrs

2. Mechanical Properties

ASTM B574 specifies strict mechanical property requirements for Hastelloy C276 round bars, ensuring reliability under static and dynamic loads. The values below apply to bars in the solution-annealed condition (typical heat treatment: 1150 - 1200°C, rapid quenching), the most common state for industrial use:

 

Property Test Standard Minimum Requirement Typical Value
Tensile Strength (UTS) ASTM E8/E8M 690 MPa (100 ksi) 750 MPa
Yield Strength (0.2% offset) ASTM E8/E8M 275 MPa (40 ksi) 310 MPa
Elongation (in 50mm) ASTM E8/E8M 40% 45%
Hardness (Brinell) ASTM E10 ≤ 217 HB 190 - 210 HB

 

Note: For cold-worked bright bars, mechanical properties (e.g., tensile strength, hardness) may be slightly higher due to work hardening, while elongation may decrease marginally. Custom heat treatment (e.g., stress relieving) can be provided upon request.

3. Equivalent Grades

Hastelloy C276 is recognized globally under various standard designations, facilitating material selection across different regions and industries. The key equivalent grades are:

 

  • ASTM (USA): UNS N10276
  • EN (Europe): DIN 17750 NiMo16Cr15W (WS 9903), EN 10095 NiCr21Mo14W
  • JIS (Japan): JIS G4902 NW276
  • GB (China): GB/T 15007 N06276
  • ISO: ISO 6363-3 NiCr21Mo14W

 

These grades share similar chemical and mechanical properties with ASTM B574 Hastelloy C276, ensuring interchangeability in most applications (e.g., chemical processing, oil and gas).

4. Machining & Customization Services

To meet diverse application needs, we offer comprehensive processing services for Hastelloy C276 round bars, leveraging advanced equipment and expertise in superalloy machining (note: Hastelloy C276 has high work hardening tendency; specialized tools are required):

 

  • Precision Cutting: Custom length cutting (from 100mm to 6000mm) via sawing, laser cutting, or waterjet cutting, with tolerance as tight as ±0.1mm.
  • Turning & Milling: CNC turning (to achieve cylindrical accuracy of IT6-IT7) and milling (for slots, grooves, or custom profiles) for components like valves, shafts, and fittings.
  • Drilling & Tapping: High-speed drilling (for holes with diameter ≥2mm) and tapping (M3-M50 threads) to meet assembly requirements.
  • Surface Treatment: Additional finishes beyond black/bright bar, including pickling (to remove oxide scales), passivation (to enhance corrosion resistance), and electroplating (e.g., nickel plating for aesthetic or wear needs).
  • Heat Treatment: Custom solutions such as solution annealing, stress relieving, or aging (per customer specifications for high-temperature or high-pressure applications).

5. Packaging & Transportation

To ensure the round bars arrive in intact, corrosion-free condition, we adopt industry-leading packaging and logistics practices:

Packaging

  • Inner Protection: Each bar is wrapped in moisture-proof VCI (Volatile Corrosion Inhibitor) film to prevent rust during storage and transit. Bright bars are additionally wrapped in soft foam to avoid surface scratches.
  • Outer Packaging:
    • For small diameters (6-50mm): Packed in strong seamless steel tubes or corrugated cardboard boxes (max weight per package: 50kg).
    • For large diameters (50-340mm): Bundled with galvanized steel straps (4-6 straps per bundle) and placed on wooden pallets (heat-treated to IPPC/ISPM 15 standards for international shipping) to prevent shifting.
  • Labeling: Each package is labeled with product details (grade, diameter, length, heat number, ASTM B574 standard), batch number, and safety warnings (e.g., "Heavy Load," "Keep Dry").

Transportation

  • Domestic Shipping: Via truck (for bulk orders) or express delivery (for small batches), with door-to-door service available.
  • International Shipping: Via sea freight (FCL/LCL, main ports: Shanghai, Ningbo, Rotterdam, Houston) or air freight (for urgent orders). All shipments include certificates of conformity (CoC), material test reports (MTRs per ASTM B574), and customs documents (commercial invoice, packing list, bill of lading).
  • Storage Recommendation: Store in a dry, well-ventilated warehouse, away from corrosive substances (e.g., acids, alkalis) and direct sunlight. Avoid prolonged exposure to high humidity to prevent surface oxidation.

6. Typical Applications

Owing to its superior corrosion resistance and mechanical stability, ASTM B574 Hastelloy C276 round bars are widely used in:

 

  • Chemical processing (reactors, heat exchangers, pipes for sulfuric acid, hydrochloric acid, and organic acids).
  • Oil and gas industry (downhole components, wellheads, and pipelines for sour gas environments).
  • Pharmaceutical and food processing (equipment requiring high purity and corrosion resistance).
  • Environmental engineering (flue gas desulfurization systems, wastewater treatment equipment).
  • Aerospace and power generation (high-temperature components in gas turbines and nuclear power plants).
