Introduction
N08800 is solid solution nickel chromium iron alloys with smaller Titanium and copper and also named 800 alloy/Incoloy 800/NCF800），The chemical composition make N08800 have excellent anti-oxidation and anti-carburization properties at high temperatures,This material is Known for its excellent high temperature corrosion resistance and good processing performance, it is suitable for manufacturing corrosion-resistant equipment. Incoloy 800/800H/800HT has resistance to acids similar to austenitic stainless steels. It has excellent resistance to both oxidising and non oxidising salts as higher Chromium composition.

Advantage：
(1) Processing performance: N08800 has good processing performance and can be formed by cold and hot processing, including welding, casting, heat treatment and machining.
(2) Corrosion resistance: N08800 has better corrosion resistance than austenitic stainless steel and Inconel 600 alloy. In the manufacture of corrosion-resistant stress cracking equipment, it is better than Inconel 600 and Monel 400 alloy.
Application：
(1) Chemical industry: it is used to manufacture nitric acid coolers, acetic anhydride cracking tubes, heat exchange equipment, etc.
(2) Nuclear energy industry: due to its high temperature and radiation resistance, it is used to manufacture fuel elements and pressure vessels for nuclear reactors.
(3).Aerospace: N08800 is used to manufacture high-temperature engine parts and propulsion system parts.
(4) Energy field, it is used to manufacture fuel elements and reactor pressure vessels for nuclear reactors.
INCOLOY 800/800H/800HT have similar chemical compositions and have good resistance to corrosion in reducing, oxidizing, nitriding media and corrosion resistance in redox alternating media. Especially in chlorides, low-concentration NaOH aqueous solutions and high-temperature and high-pressure water. N08800 also exhibits good resistance to stress corrosion cracking.
