Alloy 625 exhibits excellent corrosion resistance in many media. It has excellent resistance to pitting, crevice corrosion, intergranular corrosion and erosion in chloride media. It has good resistance to inorganic acid corrosion, such as nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid, etc., and also has resistance to alkali and organic acid corrosion in oxidizing and reducing environments. Effective resistance to chloride ion reduction stress corrosion cracking. It hardly produces corrosion in seawater and industrial gas environments, and has high corrosion resistance to seawater and salt solutions, even at high temperatures. No sensitivity during welding. It is resistant to carbonization and oxidation in static or cyclic environments, and is resistant to chlorine-containing gas corrosion.

Overall, Nickel-based alloy 625 is a versatile, high-performance alloy whose excellent physical and chemical properties make it one of the preferred materials in many fields, capable of providing reliable performance and long-term durability in extreme environments.
