Inconel 625 bolt uesd in steam liner bellows and sheathing for undersea communication cables
High solution anneal, a treatment at 2000/2200oF (1095/1205oC) for a time depending upon section size, but soaking for a maximum of one hour, and cooling in air or a faster medium.
Besides its incredible strength, alloy 625 is known for its resistance to corrosion, resistance to oxidizing, and many other corrosive elements. Alloy 625 is a nickel-chromium-molybdenum alloy used for its high strength, excellent fabricability and outstanding corrosion resistance. Service temperatures can range from cryogenic to 980¡ãC (1800¡ãF).Moreover, it is very strong and is characterized by the wide range of its fabrication possibilities.
