Incoloy 800h Seamless Pipe Astm B407 N08810 Nickel Lron Chromium Alloy

INCOLOY 800H SEAMLESS PIPE ASTM B407 N08810 NICKEL LRON CHROMIUM ALLOY

The B407 UNS N08810 tube refers to a seamless alloy tube that conforms to the ASTM B407 standard and is made from UNS N08810 material, which is commonly known as Incoloy 800H. Below is a detailed explanation:

• Composition: This alloy is a high-performance nickel-iron-chromium alloy with controlled levels of carbon, aluminum, and titanium.

  • Nickel (30–35%)
  • Chromium (19–23%)
  • Iron (remainder, ~39.5%)
  • Carbon (0.05–0.10%)
  • Aluminum (0.15–0.60%)
  • Titanium (0.15–0.60%)

• Key Properties:

  1. High-temperature strength: Designed for use in high-temperature environments up to 1100°F (593°C), offering excellent creep and stress rupture resistance.
  2. Corrosion resistance: Exceptional resistance to oxidation and carburization at high temperatures.
  3. Thermal stability: Excellent metallurgical stability due to controlled carbon, aluminum, and titanium content.
  4. Good weldability: Can be welded using standard techniques, making it versatile in industrial applications.

Advantage characteristics of Incoloy 800H/HT:

• High temperature strength
• High creep rupture strength
• Resistant to oxidation and carburization in high temperature environments
• Good corrosion resistance in many acidic environments
• Good resistance to many sulfur-containing atmospheres

Due to its high-temperature and corrosion-resistant properties, B407 UNS N08810 tubes are commonly used in:

• Petrochemical and chemical processing:
  • Heat exchangers, piping systems, and reactor components.
• Power plants:
  • Superheater and reheater tubing.
• Industrial furnaces:
  • Heating elements, radiant tubes, and furnace linings.
• Refineries:
  • Hydrocarbon processing equipment exposed to high temperatures.
•
