Inconel 725 hex nuts are an excellent choice for the petrochemical and processing industries. They are also commonly used for marine applications requiring high strength fasteners that are able to resist corrosion, pitting and crevice attack in sea water.

KD Fasteners, Inc.’s Inconel 725 hex nuts have high strength, high ductility, toughness and resistance to corrosion.

In fact, Inconel 725 hex nuts are twice the strength of Inconel 625 thanks to its heat treatment. Made with nickel, chromium, molybdenum, and niobium, Inconel 725 is an age-hardenable alloy that has essentially the same corrosion resistance as Inconel 625. Importantly, Inconel 725 is resistant to hydrogen embrittlement and stress-corrosion cracking.
