INCONEL 718/825 FASTENERS are fasteners made up of combining chromium and nickel, were chromium and nickel act as the base. However, what makes INCONEL 718/825 FASTENERS different is that they also have iron in their chemical composition and nickel. Therefore, here unlike the rest, the bases are chromium, nickel as well as iron.


As these INCONEL 718 Coated FASTENERS consist of chromium and nickel, they are eventually corrosion resistant. These additions also have molybdenum titanium and copper in their chemical composition. INCONEL 718/825 FASTENERS can stand at higher temperatures before prevents oxidation and can withstand different acidic environments, and thus these can be used in a variety of applications. Also, INCONEL 718/825 FASTENERS are relatively cheaper and can withstand upto 800 degrees Fahrenheit.

INCONEL 825 Head Hex FASTENERS have excellent resistance to oxidizing and reducing acids and work very well in environments containing sulfuric and phosphoric acids. These can be used both at average temperature and at higher temperatures which can be about 100 degrees Fahrenheit. INCONEL 718/825 FASTENERS are used in various industries such as oil, chemical, acid, etc. Since it is used in many industries because of its anti corrosive properties, it is also used in many industries because of its property of being resistant to aqueous corrosion.
