George Metals, a reputable manufacturer and supplier of high-performance Super Duplex Steel Bars and Rods, is situated in Houston, USA. These products are well-known for their remarkable strength, resistance to corrosion, and resilience in challenging conditions. They are designed for crucial uses in the chemical processing, marine, and oil and gas sectors. George Metals is dedicated to quality control and precision engineering, producing bars and rods that satisfy both client-specific requirements and global standards. The business is a dependable partner for industrial-grade metal products in demanding industries because it also provides custom solutions supported by prompt delivery and first-rate customer service.
Super Duplex Steel Bars and Rods are made of high-alloy stainless steel, which normally contains 20–30% chromium, 4–7% nickel, and 3–5% molybdenum. Iron and trace elements make up the remaining percentage. Superior resistance to stress corrosion cracking, crevice corrosion, and pitting caused by chloride is conferred by this composition. They have outstanding mechanical qualities, such as high yield strength, tensile strength of up to 800 MPa, and superior resistance to oxidation and heat fatigue. They are perfect for use in demanding industrial settings with high temperatures and stress levels because of their dual-phase (austenitic-ferritic) microstructure, which increases toughness.

Super Duplex Steel rods are generally resistant to galvanic corrosion due to their high chromium and molybdenum content. However, they can still be susceptible when coupled with highly dissimilar metals in certain environments.
Yes, Super Duplex Steel bars can be welded using appropriate techniques and filler materials. Careful control of heat input and post-weld heat treatment is essential to avoid degradation of their mechanical properties.
Super Duplex Steel rods are available in various sizes, ranging from small diameters to large rods, typically up to 300mm or more. Finishes can include hot-rolled, cold-drawn, polished, or ground, depending on the application requirements.
Super Duplex Steel Bars and Rods are widely used in industries that demand exceptional corrosion resistance and mechanical strength. They are essential for pipelines, risers, and pressure vessels exposed to harsh conditions in the oil and gas industry. They are used in heat exchangers, pumps, and reactors in the chemical processing industry. These bars are utilized in offshore platforms and structural elements in the maritime industry because they are resistant to seawater corrosion. For energy production and desalination plants, where strength, longevity, and dependability are crucial for vital operations, their capacity to tolerate high pressure, stress corrosion, and fatigue makes them appropriate.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
