Inconel 625 Superalloy
Inconel 625 is a nickel-based high temperature deformation alloy, mainly niobium and molybdenum elements as strengthening elements. Inconel 625 superalloy has very good corrosion resistance and is an excellent material in the resistance to crevice corrosion and crack resistance, and has a high degree of resistance in acidic media and organic acids.
1.Characteristics Of Inconel 625 Superalloy
- 1. Strong corrosion resistance, gap corrosion and corrosion between crystals.
- 2. Excellent mechanical properties can be maintained at high and low temperatures.
- 3. Almost completely immune to stress corrosion cracks caused by chlorine gas.
- 4. High temperature to 1050 degrees Celsius, with high antioxidant capacity.
- 5. Good acid resistance, high heat transfer in the construction of thin structure in the environment of acid and alkali medium.
