Russ Fasteners produces and offers tough Duplex Steel Nuts in Singapore, Pulau Ujong, for dependable fastening parts to support high-stress corrosive environments. These nuts are manufactured using high-quality duplex stainless steels like UNS S31803 and S32205 that possess high mechanical strength and superior resistance to corrosion, particularly in acid and chloride-bearing environments. Russ Fasteners certifies Duplex Steel Nuts with high standards of international quality for dimensional tolerance and performance. They are perfect for flanged joints and structural assemblies in oil & gas, marine, petrochemical, desalination, and pulp & paper industries.
Duplex Steel Nuts consist of around 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, with a ferrite-austenite microstructure. The two-phase metallurgy offers tensile strength of 650–800 MPa and good yield strength, almost twice that of conventional austenitic stainless steels. The nuts possess superior resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. They can retain mechanical properties under elevated temperatures and high pressure. Their strength-to-weight ratio is high, which renders them suitable for heavy-duty use without extra bulk, coupled with superior load-carrying capacity and resistance to vibration.
