ASTM B407 N08811(800H) Nickel Alloy Tubes: High-Performance Solution for Corrosion & Heat Resistance


Product Overview


ASTM B407 N08811 nickel alloy tubes are premium-grade seamless pipes designed for extreme environments requiring exceptional resistance to oxidation, carburization, and thermal stress. As a nickel-iron-chromium alloy, N08811 delivers superior performance in high-temperature applications up to 1,100°C (2,012°F), making it ideal for industrial furnaces, petrochemical processing, and energy systems.

Chemical Composition of N08811 Nickel Alloy Tubes
The optimized composition ensures stability under aggressive conditions:

  • Nickel (Ni): 44-46%
  • Chromium (Cr): 19-23%
  • Iron (Fe): Balance
  • Copper (Cu): ≤0.50%
  • Aluminum (Al): ≤0.30%
  • Titanium (Ti): ≤0.30%
  • Carbon (C): ≤0.10%
  • Manganese (Mn): ≤1.50%
  • Sulfur (S): ≤0.015%
  • Silicon (Si): ≤1.00%

Equivalent Grades to ASTM B407 N08811
Globally recognized cross-standards ensure material interchangeability:

  • UNS: N08811
  • EN (Europe): 2.4858
  • DIN (Germany): W.Nr. 1.4958
  • Other Names: Alloy 800H (similar but distinct; N08811 includes controlled Ti/Al ratios).

Mechanical Properties of N08811 Alloy Tubes
Guaranteed performance metrics per ASTM B407:

  • Tensile Strength: ≥550 MPa (80,000 psi)
  • Yield Strength (0.2% Offset): ≥240 MPa (35,000 psi)
  • Elongation: ≥30% (in 50mm)
  • Hardness: ≤90 HRB
  • Operating Temperature Range: -200°C to +1,100°C (-328°F to +2,012°F)

Tubes are supplied in an annealed condition for optimal ductility and weldability.

Key Applications of N08811 Nickel Alloy Tubes
Widely trusted in critical industries for its reliability:

  1. Petrochemical: Ethylene cracking furnace tubes, reformer manifolds.
  2. Heat Treatment: Radiant tubes, retorts, muffles for carburizing/sintering.
  3. Power Generation: Superheater tubes, boiler components in coal/nuclear plants.
  4. Chemical Processing: Reactor tubing, heat exchangers handling corrosive media.
  5. Aerospace: Combustion chamber liners, exhaust systems.

Why Choose Our ASTM B407 N08811 Tubes?

  • Precision manufacturing to ASTM/ASME SB-407 specifications.
  • Full traceability with Mill Test Certificates (EN 10204 3.1).
  • Custom sizes: OD 6mm to 250mm, thickness 1mm to 20mm.
  • Surface finishes: Pickled, polished, or sandblasted per request.
