When your infrastructure faces relentless exposure to saltwater, hydrofluoric acid, or high-stress chemical processing, standard fasteners fail. At Horizon Metal and alloy , we manufacture MONEL® Alloy 400 fasteners (UNS N04400) specifically engineered to maintain their mechanical integrity in the most hostile environments on earth.
Crafted from a solid-solution nickel-copper alloy, our MONEL 400 fasteners deliver high strength and toughness over a wide temperature range, resisting oxidation up to 1000°F (538°C). Unlike many materials, they do not undergo a ductile-to-brittle transition even at cryogenic temperatures.
