Marsh Nickel Alloys, located in Canberra, Australia, stands out as a leading manufacturer and supplier of Super Duplex Steel Wire, celebrated for its outstanding quality and dependability. With years of experience in metallurgy and precision engineering, the company guarantees that every wire adheres to strict international standards. Their Super Duplex Steel Wire merges the best features of austenitic and ferritic stainless steel, delivering remarkable strength, resistance to corrosion, and long-lasting durability. Trusted by various industries, Marsh Nickel Alloys caters to applications that demand robust performance in extreme conditions, providing products that shine in both mechanical integrity and long-term operational efficiency.
Super Duplex Steel Wire consists of approximately 25–26% chromium, 6–7% nickel, and 3–4% molybdenum, along with trace amounts of nitrogen, manganese, and iron. This well-balanced composition results in a dual-phase microstructure of austenite and ferrite, which offers high tensile strength, excellent toughness, and remarkable resistance to stress corrosion cracking. With yield strength often surpassing 550 MPa and ultimate tensile strength around 900 MPa, it can endure significant mechanical stress and harsh environments. Its low thermal expansion and exceptional fatigue resistance make it perfect for demanding industrial and marine applications.
