Neith Metals is a leading manufacturer and supplier located in Cairo, Egypt, with a focus on producing top-notch Duplex Steel Forgings. Known for their precision engineering and outstanding durability, Neith Metals crafts forgings that strike the perfect balance between high strength and remarkable corrosion resistance. Utilizing cutting-edge technology and rigorous quality control, their Duplex Steel Forgings adhere to international standards, guaranteeing dependable performance even in tough industrial settings. These forgings find extensive use in sectors like chemical processing, oil and gas, marine, and power generation, delivering long-lasting durability, resistance to harsh and corrosive environments, and excellent mechanical performance for critical applications.
Duplex Steel Forgings consist of 22–25% chromium, 4–6% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, with the remainder being iron, along with trace amounts of manganese and silicon. This dual-phase stainless steel features a mix of austenitic and ferritic microstructures, providing a tensile strength ranging from 700 to 900 MPa, a yield strength of about 450 MPa, and an elongation of 25%. It showcases exceptional resistance to pitting, crevice, and stress corrosion cracking, along with high toughness, fatigue resistance, and dimensional stability in demanding and corrosive conditions.

Verify duplex steel forgings' quality by checking certifications, such as ASTM or ISO standards, conducting material testing (e.g., tensile, hardness, corrosion resistance), and inspecting for consistent dimensions, surface finish, and proper labeling.
Yes, duplex steel forgings are highly resistant to corrosion due to their unique blend of austenitic and ferritic microstructures, providing excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
The maximum operating temperature for duplex steel forgings typically ranges from 250°C to 300°C (482°F to 572°F), depending on the specific grade and application, to maintain optimal mechanical properties.
Duplex Steel Forgings are extensively utilized in industries that demand high strength, durability, and corrosion resistance. They are commonly found in chemical processing equipment, heat exchangers, pressure vessels, and piping components. In the oil and gas sector, these forgings are perfect for valves, flanges, and offshore structures that face harsh chemicals and seawater. Moreover, they are employed in marine engineering, desalination plants, pulp and paper industries, and power generation equipment. Their unique combination of mechanical strength, corrosion resistance, and reliability ensures they perform exceptionally well in critical and challenging industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
