Neith Metals, based in Cairo, Egypt, has made a name for itself as a leading manufacturer and supplier of Super Duplex Steel Forgings. These products are celebrated for their remarkable strength, resistance to corrosion, and long-lasting durability. The company is committed to crafting high-quality forged items that adhere to international standards, catering to a diverse array of industrial needs. With cutting-edge manufacturing technology, rigorous quality control, and a talented workforce, Neith Metals guarantees precision and dependability in every single forging. They serve various sectors, including oil & gas, marine, petrochemical, and construction, and have built a solid reputation for excellence, innovation, and customer satisfaction both in Egypt and around the globe.
Super Duplex Steel Forgings are made up of chromium (25%), nickel (7%), molybdenum (4%), and nitrogen, which together create a unique dual-phase microstructure of austenite and ferrite. This special blend gives these forgings outstanding mechanical strength, exceptional corrosion resistance, and impressive toughness. They typically boast high tensile and yield strength, ranging from 800 to 1000 MPa, along with remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. Their low thermal expansion, high fatigue resistance, and structural stability make them perfect for demanding and high-pressure industrial settings.

To verify the quality of Super Duplex Steel forgings, check for certifications like ASTM, ASME, or ISO standards. Conduct tests such as mechanical property testing, chemical composition analysis, and non-destructive testing (NDT) like ultrasonic or magnetic particle inspections.
Compatible welding processes for Super Duplex Steel forgings include Tungsten Inert Gas (TIG), Metal Inert Gas (MIG), Shielded Metal Arc Welding (SMAW), and Submerged Arc Welding (SAW), using appropriate filler materials.
Super Duplex Steel forgings are governed by standards such as ASTM A182, ASTM A240, ASME SA-182, ASME SA-240, and EN 10088-3, which define material properties, chemical composition, and mechanical requirements.
These Super Duplex Steel Forgings find extensive use in industries that require top-notch mechanical performance and corrosion resistance. In the oil & gas sector, they are essential for valves, flanges, connectors, and subsea equipment. The marine industry relies on them for propeller shafts, fasteners, and components that come into contact with seawater. In the chemical and petrochemical fields, these forgings are utilized in pressure vessels, pumps, and heat exchangers. Moreover, they are widely applied in construction, desalination, and the paper & pulp industries, ensuring lasting reliability, safety, and performance even in the toughest operational conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
