Aiman Metals stands out as a reliable manufacturer and supplier of Duplex Steel Bars and Rods, proudly based in Kuala Lumpur, Malaysia. Known for their commitment to quality, the company delivers metal products that meet the demanding needs of various industries. With a strong emphasis on durability, precision, and resistance to corrosion, Aiman Metals provides a wide selection of Duplex Steel bars and rods that adhere to international standards. Their dedication to advanced manufacturing processes and rigorous quality control has established them as a go-to supplier throughout Malaysia and Southeast Asia for those in search of dependable duplex steel solutions for both structural and mechanical uses.
Duplex Steel Bars and Rods are crafted from a well-balanced blend of austenitic and ferritic stainless steels, typically featuring around 22–25% chromium, 5–7% nickel, 3–5% molybdenum, and nitrogen to boost strength and corrosion resistance. This unique dual-phase structure results in exceptional mechanical properties, including a yield strength that can be twice that of standard austenitic stainless steels. Typical mechanical values include a yield strength of 450–550 MPa, tensile strength of 700–900 MPa, and impressive elongation of 25–30%. These characteristics make Duplex Steel bars and rods particularly ideal for high-stress, corrosive environments while ensuring good weldability and toughness.
