What is Incoloy 825 used for?

As you can see, INCOLOY alloy 825 has been carefully produced to give it a range of properties that make it useful in the chemicals industry. It’s also used in pollution control, oil and gas recovery, acid production, pickling operations, nuclear fuel reprocessing and handling radioactive waste.

What is Incoloy 825?

Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. It is an alloy that provides high levels of corrosion resistance to both moderately oxidizing and moderately reducing environments. Alloy 825 is similar to alloy 800 but has improved resistance to aqueous corrosion. Incoloy 825 is a nickel-iron-chromium alloy that is highly resistant to corrosion and has excellent mechanical properties. This alloy is used in a variety of industries where resistance to extreme temperatures and corrosive environments is necessary. One of the primary applications of Incoloy 825 is in the chemical processing industry. The alloy’s high resistance to corrosion makes it an ideal material for handling corrosive chemicals, acids, and alkalis.

Here are some international grades similar to Incoloy 825:

NS142 (China), NC21FeDu (France), W.N r.2.4858 NiCr21Mo (Germany), NA16 (UK), Incoloy 825, UNS NO8825 (USA), and NiFe30Cr21Mo3 (ISO).

Incoloy825 main application fields

Incoloy 825 is commonly used in heat exchangers, piping, and storage tanks in chemical processing plants.

Incoloy 825 is also used in the oil and gas industry, particularly for equipment that is exposed to highly corrosive environments, such as offshore drilling platforms and pipelines. It is used in components such as valves, pumps, and wellhead equipment that require high strength and corrosion resistance. The alloy is also commonly used in the aerospace industry, where its high strength-to-weight ratio and resistance to high temperatures make it an ideal material for gas turbine components, exhaust systems, and other critical aircraft parts.

Incoloy 825 is also used in the marine industry, particularly in seawater desalination plants, where its resistance to corrosion and high temperatures is essential. It is used in components such as heat exchangers, piping, and valves in these plants.

In addition to these industries, Incoloy 825 is used in a variety of other applications, including nuclear power plants, pollution control equipment, and medical equipment.

In conclusion, Incoloy 825 is a highly versatile and valuable material that is used in a wide range of industries and applications. Its unique combination of properties, including high strength, excellent corrosion resistance, and resistance to extreme temperatures, make it an ideal choice for applications that require high performance in harsh environments.

What is the difference between INCOLOY 800 and 825?

Both Incoloy 800 and Incoloy 825 are solid solution strengthened alloys. Because some molybdenum is added to 825 to make the solid solution strengthening effect better, its overall strength will be higher. But there is no obvious difference in strength between the two alloys. They mainly differ in corrosion resistance.
