George Metals, located in Houston, USA, has built a solid reputation as a reliable manufacturer and supplier of Duplex Steel Rectangular Bars. These bars are celebrated for their impressive blend of strength, durability, and resistance to corrosion, making them suitable for a wide range of industrial needs. At George Metals, precision engineering and top-quality standards are paramount, ensuring that their products can endure tough environments while providing long-lasting performance. With a strong commitment to excellence, the company offers customized solutions for various sectors, including oil and gas, petrochemical, and construction, positioning Duplex Steel Rectangular Bars as a dependable choice for demanding applications.
Duplex Steel Rectangular Bars are crafted from a well-balanced blend of austenitic and ferritic stainless steel, typically containing chromium (21-23%), nickel (4.5-6.5%), molybdenum (2.5-3.5%), and nitrogen. This distinctive composition results in impressive tensile strength (minimum 620 MPa) and yield strength (minimum 450 MPa), along with outstanding resistance to stress corrosion cracking and pitting. The dual-phase microstructure guarantees excellent toughness, weldability, and stability in harsh environments, such as those with acidic or saline conditions.
