Phehlukwayo Metal, located in Cape Town, South Africa, has earned a solid reputation as a reliable manufacturer and supplier of top-notch metal products, including the sturdy Super Duplex Steel Square Bar. Renowned for their excellence in metallurgy, Phehlukwayo Metal serves a variety of industries with precision-engineered solutions that are built to endure even the harshest environments. With a strong focus on quality, reliability, and customer satisfaction, the company provides an extensive range of Super Duplex Steel products that meet international standards. Their expertise, combined with cutting-edge manufacturing techniques, ensures that clients receive materials optimized for strength, durability, and corrosion resistance, especially in critical industrial applications.
The Super Duplex Steel Square Bar boasts a well-balanced chemical composition, typically featuring around 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, all contributing to its ferritic-austenitic microstructure. This unique composition significantly boosts its resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, it delivers impressive tensile strength (up to 800 MPa), excellent yield strength, and outstanding fatigue resistance. Thanks to its dual-phase structure, it offers enhanced toughness and durability compared to standard duplex steels, making it perfect for demanding applications in aggressive environments, such as marine and chemical processing industries.
