Description

ASTM B407/ ASME SB407 Incoloy 800H / UNS N08811 Nickel Alloy Seamless Tube

ASTM B407 UNS N08811 (Incoloy 800HT) seamless tube is prized for its ability to withstand extreme temperatures, corrosive environments, and mechanical stress. Below are some reasons why choose UNS N08811 over alternative:

Scenario N08811 Advantage Alternative Material Limitation of Alternative
Ethylene Cracking (1100°C) Resists carburization and thermal fatigue SS 310H Lower creep strength at 1000°C+
Steam Reforming (900°C) Higher creep rupture strength Incoloy 800H (N08810) Lower carbon content reduces strength
Sour Gas (H₂S) NACE compliance and SCC resistance Duplex Stainless Steel Prone to H₂S-induced cracking
Molten Salt Heat Transfer Oxidation resistance in air Inconel 625 Overkill for non-corrosive salts

Manufacturing & Processing

  • Seamless Tube Production:

    • Hot Extrusion: Billets heated to 1100–1200°C and forced through a die to form hollow tubes.

    • Cold Drawing: Final dimensions achieved through cold working for precise tolerances and surface finish.

    • Heat Treatment: Solution annealed at 1150–1200°C followed by rapid quenching to dissolve carbides and ensure uniform microstructure.

Application

1. Petrochemical & Chemical Processing

  • Ethylene Cracking Furnaces

  • Steam Methane Reformers (SMRs):

  • Pyrolysis Units

2. Power Generation

  • Fossil Fuel Power Plants:

  • Heat Recovery Steam Generators (HRSGs)

  • Nuclear Power Plants:

3. Oil & Gas (Upstream/Downstream)

  • Sour Gas Processing

  • Flare Systems:

4. Industrial Furnaces & Heat Treatment
