Monel 400 Forged Fittings are primarily made up of nickel (around 63%) and copper (approximately 28–34%), along with small amounts of iron, manganese, and silicon. This solid-solution alloy is known for its excellent resistance to seawater, hydrofluoric acid, and alkaline conditions. Monel 400 boasts a tensile strength ranging from 480 to 620 MPa, a yield strength between 170 and 275 MPa, and an elongation of about 35%. The forged construction improves the grain structure, ensuring superior mechanical integrity, impact resistance, and precise dimensions, even in high-pressure and elevated-temperature situations. These characteristics make Monel 400 perfect for demanding industrial and marine applications.
