These nuts are primarily made from chromium, nickel, and molybdenum, with a touch of nitrogen to boost their mechanical strength and corrosion resistance. Their unique dual-phase microstructure, which combines ferrite and austenite, offers outstanding protection against stress corrosion cracking, pitting, and crevice corrosion. On the mechanical side, they deliver high tensile and yield strength, toughness, and fatigue resistance, maintaining stability even under fluctuating temperatures, high pressures, and cyclic loads. This blend of mechanical strength and chemical resistance makes them a perfect fit for critical industrial applications.
Duplex Steel S31803 Nuts find extensive use in industries that face harsh chemical and marine conditions. In chemical and petrochemical plants, they are utilized in reactors, piping systems, and heat exchangers that handle aggressive fluids.
