Duplex Steel Fasteners S31803 are composed of around 22% chromium, 5–6% nickel, and 3% molybdenum, with additions of nitrogen to enhance strength and corrosion resistance. This duplex microstructure provides a perfect balance of austenitic and ferritic properties. These fasteners exhibit high tensile strength (approximately 620–880 MPa) and excellent yield strength (around 450 MPa). They also possess superior resistance to stress corrosion cracking, pitting, and crevice corrosion, making them suitable for high-pressure and high-temperature environments.
