Elvis Nickel Alloys, a top-notch manufacturer and supplier located in Houston, USA, specializes in high-quality Super Duplex Steel Bars that are built for strength, corrosion resistance, and durability in even the toughest industrial settings. These bars are crafted from premium alloys like UNS S32750 (SAF 2507) and UNS S32760 (Zeron® 100), showcasing a well-balanced dual-phase austenitic-ferritic microstructure. This design provides exceptional resistance to pitting, crevice corrosion, chloride stress corrosion cracking, and erosion fatigue. You can find them in various shapes, including round, square, hexagonal, and flat bars, all adhering to global standards like ASTM A276, ASTM A479, and EN 10088-3.
Super Duplex Steel Bars are made up of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, 0.2–0.3% nitrogen, along with trace elements like copper, manganese, and tungsten. These components give the bars a Pitting Resistance Equivalent Number (PREN) greater than 40, ensuring they resist localized corrosion exceptionally well. They can handle tensile strengths of up to 800 MPa and yield strengths of at least 550 MPa, all while maintaining excellent impact toughness, even in low temperatures. Their impressive mechanical strength and corrosion resistance make them perfect for both static and dynamic load-bearing applications in harsh conditions.
