Duplex Steel Welding Wire generally consists of 21–23% Chromium, 8–10% Nickel, 3–5% Molybdenum, 0.10–0.30% Nitrogen, with the remainder being Iron, plus some small amounts of Manganese and Silicon. A balanced chemistry provides a duplex microstructure of ferrite and austenite, which gives this material superior resistance to corrosion, pitting, and stress cracking. Its mechanical properties consist of tensile strength of approximately 700–850 MPa, yield strength of 450–550 MPa, and elongation of 25–30%, which translates to high strength with good ductility. Duplex steel wire is perfect for the type of project that requires exceptional toughness and durability in hostile environments.
At Ragnar Welding Supplies, we take pride in being one of Indonesia’s trusted suppliers of high-quality welding consumables. Our expertise lies in Duplex Steel Welding Wire, engineered for precision, durability, and resistance to corrosion. With a strong commitment to quality and customer satisfaction, we provide welding solutions that support industries across construction, energy, shipbuilding, and manufacturing.
Duplex Steel Welding Wire is commonly utilized in situations that demand high strength, corrosion resistance, and reliability. It is well-suited for offshore structures, oil and gas pipelines, pressure vessels, processing plants, systems for desalination of seawater, and marine equipment. This wire provides excellent pitting and crevice corrosion resistance and stress corrosion cracking resistance due to its unique dual-phase microstructure. Hence, this wire is ideal for very harsh environments, especially in chloride-rich atmospheres. Duplex welding wire can also be used in heat exchangers and storage tanks, as well as for structural fabrication in all types of operations where the mechanical performance of the weld, and corrosion protection, are important considerations. The Welding Wire provides a strong, reliable, long-lasting weld in demanding and complex industrial operations around the world.
