Inconel 725/N07725

Inconel 725 alloy overview:

Inconel 725 alloy is a nickel-chromium-molybdenum-niobium alloy, which has excellent corrosion resistance. After aging heat treatment, it can greatly increase the strength of the alloy and greatly improve the ductility and tensile resistance of the alloy. The alloy also has strong resistance to stress corrosion.

Special alloy materials commonly used in seawater desalination:

Stainless steel: 317L, 1.4529, 254SMO, 904L, AL-6XN, etc.

Nickel-based alloys: Alloy 31, Alloy 926, Incoloy 926, Incoloy 825, Monel 400

Corrosion-resistant alloy: NS112

Corrosion-resistant alloy: The material used in the desalination process of NS112 needs to have corrosion resistance. The choice of materials and design principles depend on the service environment of the material. Stainless steel is an ideal material due to its corrosion resistance and durability, and is used in various desalination processes.
