Monel 400 Fasteners are made up of about 63% nickel and 30–34% copper, along with trace amounts of iron, manganese, carbon, and silicon. This solid-solution alloy boasts excellent corrosion resistance in marine and chemical environments, particularly against saltwater, hydrofluoric acid, and alkalis. These fasteners exhibit a tensile strength ranging from 480 to 620 MPa, yield strength between 170 and 345 MPa, and an elongation of around 30–40%. Monel 400 maintains its toughness and strength across a wide temperature range, making it perfect for fastening components that are subjected to high pressures, stress, and aggressive chemicals.
