800, 825, 901, 925, 926 Seamless Incoloy Pipe Tube Extruded, Cold Rolled

1. What is an Incoloy 800(N08800) pipe/tube?

Incoloy 800(N08800) has good rupture and creep strength and excellent resistance to oxidation, carburization, and sulfidation at temperatures up to 816 C. It also resists general corrosion by many aqueous media. For applications requiring higher stress rupture and creep properties, especially at temperatures above 816'℃, N08810 and N08811 are recommended .N08800 is readily formed, welded, and machined.

6. Applications and characteristics of Incoloy 800 pipe/tube

Performance characteristics of Incoloy 800 pipe/tube steel

Due to its many distinctive qualities, in high-temperature situations, Incoloy 800 is frequently employed. First of all, it has great oxidation resistance and can function steadily for a long time at high temperatures. Second, it has exceptional corrosion resistance and can withstand both alkaline and acidic media erosion. The substance also exhibits strong resistance to hydrogen embrittlement and stress corrosion cracking.

Many corrosive media are resistant to Incoloy 800. Due to its high nickel concentration, it resists stress corrosion cracking in harsh aqueous environments quite well. It is more resistant to pitting and crevice corrosion cracking due to the high chromium content. Although this alloy has low corrosion resistance to sulfuric and hydrochloric acids, it has considerable corrosion resistance to nitric and organic acids. It has strong corrosion resistance in oxidizing and non-oxidizing salts in addition to the potential for pitting corrosion in halides. Additionally, it has good corrosion resistance in water, steam, and steam, air, and carbon dioxide mixes.
