Adrian Nickel Alloys stands out as a trusted manufacturer and supplier of **Duplex Steel Screws** in Singapore, Pulau Ujong. They provide high-strength, corrosion-resistant fastening solutions tailored for tough industrial settings. Made from top-quality duplex stainless steel, these screws boast a well-balanced austenitic-ferritic microstructure, which gives them exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, even in challenging environments like those rich in chlorides or marine conditions. With a variety of sizes, types, and thread configurations available, these screws are precision-engineered to guarantee secure fastening, impressive dimensional accuracy, and long-lasting performance in both structural and mechanical assemblies.
Typically, **Duplex Steel Screws** contain 22–25% chromium, 5–7% nickel, 3–4% molybdenum, and nitrogen, all of which boost their mechanical strength and corrosion resistance. They deliver a tensile strength of about 620–800 MPa and a yield strength of roughly 450–550 MPa, along with excellent impact toughness, making them perfect for applications that face high mechanical stress and harsh environmental conditions.
