Inconel 625 Demister Pads
Inconel 625 Demister Pads has a corrosion resistance to many environments. In mild environments such as atmosphere, fresh water and sea water, neutral salts and alkaline media there is almost no attack. In more aggressive media nickel and chromium resist oxidizing attack, while nickel and molybdenum resist reducing environments. Molybdenum provides exceptional resistance to pitting and crevice corrosion, and niobium stabilizes against sensitization and intergranular corrosion.
The nickel content makes Inconel 625 ressentially free from chloride ion stress corrosion cracking.
Inconel 625 Demister Pads also has excellent corrosion fatigue properties.
