Nickel Alloy Flange ASTM B564 UNS N08825 Chemical Application Corrosion Resistance
What is ASTM B564 UNS N08825 Nickel alloy steel flange?
UNS N08825 alloy belongs to Ni-Fe-Cr-Mo-Cu solid solution strengthened corrosion-resistant alloy, the alloy contains high Ni and Cr elements, and at the same time a certain amount of Mo, Cu elements and stabilized Ti elements are added, so it has a good resistance to pitting corrosion, intergranular corrosion, crevice corrosion and stress corrosion cracking, and it is usually applied to Petrochemical, hydrometallurgy, chemical energy and many other industrial environments, used for heat exchangers, pipelines and other heat exchangers dealing with hot sulfuric acid, chloride-containing solutions, sulfurous acid and so on. In the high sulfur crude oil processing industry, it is widely used in hydrocracking and other corrosive equipment where severe sulfides and chlorides exist.
Characteristic of UNS N08825
CORROSION RESISTANCE: UNS N08825 flanges have excellent corrosion resistance to acidic, alkaline and saline media. It can resist the corrosion of a series of corrosive media such as sulfuric acid, nitric acid, chloride, etc. It is suitable for chemical, petroleum and marine fields.
High temperature performance: UNS N08825 flanges have stable performance in high temperature environments, and can withstand temperatures up to about 1000°C. Therefore, it is widely used in high-temperature equipment in petroleum refining, chemical and electric power industries.
Mechanical properties: UNS N08825 flanges have good mechanical properties with high strength, high toughness and good workability. This makes it able to withstand high pressure and high temperature working conditions for a wide range of industrial equipment.
STABLE CHEMICAL COMPOSITION: UNS N08825 flanges have a stable chemical composition with some resistance to thermal stress corrosion cracking. This makes it less prone to change in high temperature and corrosive environments, maintaining the stability and reliability of the material.
