What is Inconel 625 Spiral Wound Gasket?
Inconel 625 spiral wound gasket is made of Alloy 625 steel strip and soft filler such as graphite and PTFE, it has high strength and outstanding aqueous resistance to chloride pitting and crevice corrosion. The strength of alloy 625 spiral wound gasket is primarily a solid solution effect from molybdenum and columbium.Applications of Inconel 625 Spiral Wound Gasket
Inconel 625 spiral wound gasket can be used in aircraft ducting systems, jet engine exhaust systems, engine thrust-reverser systems, bellows and expansion joints, seawater components.Corrosion Resistance of Inconel Alloy 625
Inconel alloy 625 has withstood many corrosive environments. In alkaline, salt water, fresh water, neutral salts, and in the air, almost no attack occurs. The nickel and chromium provide resistance to oxidizing environments. Nickel and molybdenum provide for resistance to nonoxidizing atmospheres.Upon exposure to oxidising agents, Inconel 625 is protected naturally by its nickel-chromium matrix. Meanwhile, molybdenum protects the material against pitting corrosion. In 15% sulfuric acid, the material corrodes at a minimal rate of 0.188 mm per year.
