Chemical composition of uns n08811 pipe

Its alloy composition contains approximately 29%-35% nickel, 19%-23% chromium, with iron as the base, and also includes aluminum (0.2%-0.6%), titanium (0.6%-1.0%), and carbon (0.06%-0.10%). This precise composition ratio achieves stable performance under high-temperature conditions.

alloy 800ht High-temperature strength

Maintains outstanding tensile strength and creep rupture strength within the temperature range of 600℃-1100℃, and will not show significant deformation or breakage due to high temperatures during long-term use.

incoloy 800ht welded pipe Corrosion resistance

Incoloy N08811 pipe has good corrosion resistance to oxidizing media (such as high-temperature air and flue gas) and reducing media (such as hydrogen and carbon monoxide), and can resist corrosion from sulfides, chlorides, and other corrosive agents.

inconel 800ht pipe Oxidation resistance

A dense chromium oxide protective film forms on the surface at high temperatures, preventing further oxidation of the alloy. This protective film is not easily detached during temperature fluctuations, extending the service life of the pipe.

incoloy 800ht exw pipe Processing performance

Incoloy N08811 pipe can be cold-worked (e.g., bending, rolling) and hot-worked (e.g., forging, welding). When welding, matching nickel-based welding wire (e.g., ERNiCr-3) is used, and the performance remains stable without complex heat treatment after welding.
