Inconel 625 hex bolts offer good corrosion resistance at elevated temperatures and high temperature stability up to 2200°F. KD Fasteners Inc.’s Inconel 625 hex bolts are made with a high strength material with excellent toughness at elevated temperatures.
Also known as Alloy 625, Inconel 625 hex bolts are known for their ability to retain their strength and resist heat – both in and out of corrosive environments. The presence of nickel and chromium make Inconel 625 hex bolts corrosion, oxidation and carburization resistant. The molybdenum delivers excellent fatigue strength and resistance to stress, pitting and crevice corrosion cracking even when exposed to chloride ions.
Inconel 625’s high strength capabilities are due to the addition of molybdenum and niobium on its nickel-chromium matrix. These hex bolts are also resistant to a wide range of corrosive environments of unusual severity including sulfuric acid, hydrochloric acid and phosphoric acid.
Inconel 625 Characteristics
- Corrosion resistant
- Oxidation resistant
- Carburization resistant
- Nickel-based alloy
