Offering incredible strength, high ductility and toughness, Inconel 725 hex bolts are also highly resistant to corrosion.inconel 725 hex bolts

Inconel 725 hex bolts 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.

 Inconel 725 Characteristics

  • Resistant to stress-corrosion cracking
  • Resistant to sea water
  • Excellent fracture toughness

Inconel 725 hex bolts 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.
