Louis Metals offers best–class Super Duplex Steel 2507 Bars and Rods in Houston, USA, for ultimate strength, corrosion resistance, and longevity. UNS S32750/S32760 (also referred to as 2507) is a super duplex stainless steel offering great mechanical properties with better corrosion resistance, particularly in chloride-rich and sea water conditions. Our ASTM A479 and ASTM A276 specification 2507 bars and rods are produced to order in special sizes and surface finishes. Louis Metals assists critical sectors such as offshore drilling, marine engineering, desalination, and chemical processing with reliable, high-performance super duplex bars designed for long life.
Super Duplex 2507 is comprised of about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, which increases the pitting and crevice corrosion resistance. It yields high tensile strength (~800–860 MPa) and yield strength (~550 MPa), with high resistance to fatigue and impact. The microstructure of the dual phase (ferrite and austenite) enhances structural integrity under stress and exhibits high resistance to chloride stress corrosion cracking. The material is strong at high temperatures and weldable under controlled conditions. Louis Metals maintains close dimensional tolerances and strict quality control in each bar and rod produced.
