ASTM B407 UNS N08811 DIN / 1.4959 / INCOLOY 800HT SEAMLESS ALLOY STEEL PIPE

Incoloy 800H and 800HT are high-performance alloys that belong to the Incoloy family, which are nickel-chromium-iron alloys known for their excellent high-temperature strength and oxidation resistance. Unlike some other alloys, Incoloy 800H/800HT retains its strength under elevated temperature conditions, making it ideal for applications that face thermal cycling. The alloys can be easily fabricated, allowing for effective joining methods without much sacrifice in performance, which is essential in various industrial applications.

Key Advantages of 800 Series Alloys

  • Temperature Resistance: These alloys can withstand temperatures up to about 1800°F (982°C) with remarkable resistance to deformation.
  • Corrosion Resistance: Highly resistant to both oxidation and reduction environments, particularly beneficial in chemical processing and petrochemical applications.
  • Versatile Fabrication: Excellent weldability allows for a variety of fabrication techniques, making these alloys suitable for complex structures.
