From saltwater to acids, KD Fasteners, Inc.’s Inconel 625 heavy hex bolts hold their strength making them one of the toughest bolts on the market.
Our Inconel 625 heavy hex bolts offer excellent strength and toughness in the temperature range of cryogenic to 2000°F. Due to this ability to withstand temperature variation, Inconel 625 heavy hex bolts can be used in a variety of extreme conditions from heat shields to marine applications.
Inconel 625 Characteristics
- Corrosion resistant
- Oxidation resistant
- Carburization resistant
- Nickel-based alloy
- Cryogenic to 2000°F temperature range
- High corrosion-fatigue strength
- High tensile strength
Inconel 625’s high strength capabilities are due to the addition of molybdenum and niobium on its nickel-chromium matrix. Inconel 625 is also, therefore, resistant to a wide range of corrosive environments of unusual severity. In seawater applications, Inconel 625 heavy hex bolts remain free from pitting and crevice corrosion. This makes it ideal for marine, submarine and Navy applications. Additionally, Inconel 625 heavy hex bolts stand up strong to a wide range of environments including sulfuric acid, hydrochloric acid and phosphoric acid. Inconel 625 is even an ASME approved material of construction under the boiler and pressure vessel code.
Other applications for Inconel 625 heavy hex bolts include:
- Aerospace industry
- Chemical processing
- Nuclear industry
- Heat shields
- Seawater applications
- Nuclear power plants: core and control rod bolts
- Gas turbine engines
- Pollution control equipment
