What is Duplex Steel S31803 Fasteners?
Duplex Steel S31803 combines approximately 22% chromium, 5–6% nickel, 3% molybdenum, with small amounts of manganese, silicon, and nitrogen, providing a unique mix of austenitic and ferritic microstructures. These fasteners offer high tensile strength (≥ 680 MPa), yield strength (≥ 450 MPa), and excellent toughness. They exhibit outstanding resistance to stress corrosion cracking, pitting, and crevice corrosion, making them suitable for harsh environments. With a balanced combination of strength, durability, and corrosion resistance, S31803 fasteners are ideal for marine, chemical, and oil & gas applications.
