  • ASTM B407 ALLOY800H SMLS PIPE

ASTM B407 ALLOY800H SMLS PIPE

  • Material Standard:ASTM B407
  • Grade No.:UNS N08810
  • Type:Nickel-Iron-Chromium Alloy Seamless Pipe and Tube
  • End:Beveled End,Plain End

PRODUCT DESCRIPTION


Alloy 800H SMLS pipe has extreme heat and corrosive environments. The alloy's combination of nickel, iron, and chromium gives it exceptional resistance to oxidation, carburization, and sulfidation under harsh industrial conditions. This makes alloy 800H SMLS pipe well-suited for use in chemical, petrochemical, and power generation plants.

Alloy 800H Seamless pipe is produced without any welds or seams, which helps to enhance their strength and resistance to corrosion and other types of damage. This material is highly resistant to oxidizing and reducing environments, and it can withstand temperatures up to 1000 °C without suffering significant damage or degradation. This makes it an ideal choice for use in high-temperature applications such as furnace parts, heat exchangers, and other critical components that must withstand extreme conditions.
