Phehlukwayo Metal, based in Cape Town, South Africa, has earned a solid reputation as a top-notch manufacturer and supplier of high-quality stainless steel products, particularly their impressive Super Duplex Steel Bars and Rods. With a strong focus on quality, precision, and reliability, this company delivers advanced steel solutions tailored for industries that operate in tough environments. By utilizing cutting-edge manufacturing technologies and maintaining rigorous quality control, Phehlukwayo Metal ensures that every product aligns with international standards. Their Super Duplex Steel Bars and Rods are designed to provide exceptional strength, corrosion resistance, and long-lasting durability, making them a go-to choice for clients in marine, petrochemical, and structural engineering fields.
These Super Duplex Steel Bars and Rods are made up of about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, which together create a ferritic-austenitic microstructure. This well-balanced composition grants them remarkable resistance to chloride-induced stress corrosion cracking, pitting, and crevice corrosion. On the mechanical side, they boast high tensile strength (up to 800 MPa), impressive yield strength, and outstanding impact resistance, even in freezing temperatures. Their fatigue resistance and toughness far exceed those of standard stainless steels, making them perfect for demanding structural and corrosive applications across various heavy-duty industrial environments.

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 find their place in industries that require high strength, durability, and exceptional corrosion resistance. This includes offshore oil and gas platforms, marine settings, chemical processing, power generation, and desalination plants. Their robust nature and versatility make them ideal for use in shafts, fasteners, pump components, structural supports, and pressure vessel parts. Capable of withstanding significant mechanical stress and exposure to harsh chemicals or seawater, they are a dependable choice for critical operations. Phehlukwayo Metal guarantees that each bar and rod adheres to strict safety and performance standards.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
