Phehlukwayo Metal, based in Cape Town, South Africa, has built a solid reputation as a manufacturer and supplier of top-notch metal products, including the robust Super Duplex Steel Rectangular Bar. Renowned for its commitment to quality and precision, the company caters to a diverse array of industries, providing materials that adhere to strict international standards. With cutting-edge production capabilities and a skilled team, Phehlukwayo Metal delivers corrosion-resistant, high-strength bars that are perfect for challenging environments. Their unwavering focus on reliability and customer satisfaction has made them a go-to partner for clients in search of outstanding Super Duplex stainless steel solutions.
The Super Duplex Steel Rectangular Bar features a well-balanced blend of chromium (around 25%), nickel (7%), molybdenum (4%), and nitrogen, resulting in a dual-phase microstructure (austenitic-ferritic). This unique composition grants it remarkable resistance to chloride-induced stress corrosion cracking, pitting, and crevice corrosion. On the mechanical side, it showcases impressive tensile strength, superior yield strength, and excellent impact toughness. With a tensile strength reaching up to 800 MPa and strong fatigue resistance, it excels in harsh conditions, proving to be more durable than standard stainless steels and making it perfect for high-stress structural and chemical applications.

When selecting Super Duplex Steel Rectangular Bars, consider factors like corrosion resistance, mechanical strength, operating temperature, application environment, and compliance with industry standards for optimal performance.
Yes, Super Duplex Steel Rectangular Bars can be welded using appropriate techniques such as TIG or MIG welding. However, proper heat control is necessary to maintain their corrosion resistance and mechanical properties.
Super Duplex Steel Rectangular Bars are not ideal for cryogenic applications, as their toughness and ductility may decrease at extremely low temperatures, potentially leading to brittleness in such environments.
The Super Duplex Steel Rectangular Bar finds its place in industries that require both mechanical strength and corrosion resistance. It’s particularly suited for offshore oil rigs, marine engineering, desalination equipment, pressure vessels, heat exchangers, and chemical processing plants. Its rectangular shape makes it ideal for structural frameworks, supports, brackets, and load-bearing components in corrosive settings. Thanks to its outstanding durability and performance in extreme conditions, this alloy is a trusted choice for critical infrastructure. Phehlukwayo Metal guarantees that each bar is crafted to the highest standards, providing clients with dependable solutions for complex engineering challenges.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
