For high strength combined with excellent corrosion resistance, look no farther than Inconel 725 socket cap screws.

KD Fasteners, Inc.’s Inconel 725 socket cap screws are made with a nickel-chromium-molybdenum-niobium age-hardenable alloy that has essentially the same corrosion resistance as Inconel 625. However, this alloy offers twice the strength of Inconel 625. The strength of Inconel 725 is developed by heat treatment to achieve high ductility and toughness. As a result, Inconel 725 is resistant to hydrogen embrittlement and stress-corrosion cracking.
