ASTM B407 UNS N08811 / DIN 1.4958 Nickel Alloy Tube Seamless Incoloy 800HT Tube

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.
