Incoloy 800 825 Seamless Pipe

incoloy 800 825 seamless pipe

The Alloy 800 Series (Incoloy 800, 800H, and 800HT) are nickel-iron-chromium superalloys that provide high-temperature strength and resistance to oxidation, carburization, and other types of high-temperature corrosion. Alloy 800 (UNS N08800), Alloy 800H (UNS N08810) and Alloy 800HT (UNS N08811) have the same nickel, chromium and iron contents, but differ in the combined levels of titanium and aluminum (0.85 to 1.2%) to ensure optimal high temperature characteristic.
Incoloy825 alloy is a NI-FE-MO-CU corrosion-resistant alloy stabilized with Ti. The alloy has effective resistance to uniform corrosion and localized corrosion, and has good performance, so it is widely used in chemistry, energy, and hydrometallurgy. Application. In addition, the alloy has good toughness and performs well in the atmosphere. However, it should be noted that very shallow pitting corrosion will occur in humid atmosphere. This alloy is also resistant to freshwater corrosion and can be used in flowing seawater under all circumstances. However, Certain spots will appear in still seawater or under polluted conditions, so everyone should pay attention to this when producing products. The corrosion resistance of the alloy is very good in various media, such as sulfuric acid, phosphoric acid, and hydrochloric acid. , nitric acid, sulfurous acid, organic acids and compounds. Alkali metals such as sodium hydroxide, potassium hydroxide and hydrochloric acid solutions. Of particular note is the poor corrosion resistance in hydrofluoric acid.
