Do you know what Incoloy825 alloy is?

Introduction:

Alloys comparable to Incoloy 825 alloys are high Ni, highly corrosion-resistant nickel-based alloys with extremely high corrosion resistance to both oxidizing and non-oxidizing acids.

Incoloy 825 alloy has good general corrosion resistance to both oxidizing and non-oxidizing acids due to its rich content of Cr, Mo and Cu. In particular, it has extremely high corrosion resistance to sulfuric acid. Due to the high content of Cr, Mo and Ni, it has excellent pitting corrosion resistance, crevice corrosion resistance and stress corrosion cracking resistance in chloride environment. Incoloy 825 alloy controls the carbon content to a very low level, is not easily sensitized during welding, and has a low susceptibility to intergranular corrosion.

Incoloy 825 alloy has the following properties:

1. Good resistance to stress corrosion cracking

2. Good resistance to pitting and crevice corrosion

3. Good anti-oxidative and non-oxidative thermal acid properties

4. Good mechanical properties at room temperature and high temperature up to 550℃

5. Certification of pressure vessels with manufacturing temperature up to 450°C

Application areas of Incoloy825 alloy:

Heating pipes, containers, baskets and chains for sulfuric acid pickling plants, seawater cooling heat exchangers, marine product piping systems, acid gas environment piping, heat exchangers, evaporators, scrubbers, dip pipes, etc. in phosphoric acid production, petroleum Air heat exchangers in refining. Food engineering chemical processes, flame retardant alloys for high pressure oxygen applications.
