Duplex Steel Fasteners are manufactured from duplex stainless steel, which combines austenitic and ferritic microstructures to offer superior mechanical strength and corrosion resistance. The alloy typically contains chromium, nickel, molybdenum, and nitrogen, providing excellent resistance to pitting, stress corrosion cracking, and chloride-induced corrosion. Mechanically, these fasteners offer high tensile and yield strength, toughness, and reliability under extreme pressure and elevated temperatures. Precision threading, consistent dimensions, and strong structural integrity ensure secure fastening in critical applications, making them suitable for harsh industrial and marine environments.
