Phehlukwayo Metals, is based in Cape Town, South Africa, and is a quality metal product manufacturer and supplier. Phehlukwayo Metals offers an assortment of various alloys and stainless steels, thus making them durable and reliable as well as economical solutions for most industries around the world. Among its key products, it offers Super Duplex Steel Bright Bar, a material with excellent strength and durability for corrosion-resistant properties. Super Duplex Steel Bright Bar is ideal for the most demanding applications in offshore, chemical processing, and marine industries. It can provide long-term reliability, so it is an essential material for manufacturers that require superior materials for critical projects.
Super Duplex Steel Bright Bars are high-performance alloy materials that encapsulate the properties of the most commonly known austenitic and ferritic stainless steels. Containing 22-25% chromium (Cr), 4-7% nickel (Ni), 3-5% molybdenum (Mo), and approximately 0.2% nitrogen (N), the product provides excellent corrosion resistance in chloride-rich environments. The alloy provides strength generally at between 550-800 MPa with good toughness against stress corrosion cracking. The microstructure essentially comprises about 50% austenite and about 50% ferrite, which produces superior mechanical properties, including tensile strength, resistance to pitting, crevice corrosion, and high-temperature stability, that make it an excellent candidate for demanding applications.

The hardness of Super Duplex Steel Bright Bars typically ranges between 250-300 HB (Hardness Brinell), depending on the specific grade and heat treatment, offering excellent strength and resistance to wear and corrosion.
Yes, Super Duplex Steel Bright Bars can be recycled after use. Their high chromium and nickel content makes them highly recyclable, contributing to sustainability and reducing the need for new raw materials.
Super Duplex Steel Bright Bars are highly resistant to corrosion due to their high chromium and molybdenum content. However, in highly aggressive environments, additional coatings may be applied for extra protection.
This Super Duplex Steel Bright Bar is used in most high-strength, corrosion, and long-term industrial operations. Its main applications are offshore oil and gas platforms, chemical processing, and desalination plants, with the resistance of pitting, crevice, and stress corrosion cracking features of the alloy. It is also used for construction purposes in the making of heat exchangers, pressure vessels, valves, and pumps, due to mechanical strength and durability. More, Super Duplex Steel Bright Bar is suitable for marine environments, power generation, food processing, pulp and paper, where reliability and performance are most important under hard and corrosive conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
