Neith Metals is a well-respected manufacturer and supplier located in Cairo, Egypt, with a focus on producing top-notch Duplex Steel Flat Bars. Renowned for their precision engineering and remarkable durability, Neith Metals offers flat bars that blend exceptional strength with impressive resistance to corrosion. Crafted with cutting-edge technology and rigorous quality control measures, their Duplex Steel Flat Bars guarantee consistent mechanical performance, precise dimensions, and long-lasting reliability. Perfect for tough industrial applications, these flat bars find their place in the chemical, petrochemical, marine, and power generation sectors, standing up to harsh environments, high stress, and corrosive conditions while ensuring efficiency and durability.
These Duplex Steel Flat Bars are made up of 22–25% chromium, 4–6% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, with iron making up the rest, along with trace amounts of manganese and silicon. This dual-phase stainless steel showcases a mix of austenitic and ferritic structures, delivering a tensile strength of 700–900 MPa, a yield strength of about 450 MPa, and an elongation of 25%. It offers excellent resistance to pitting, crevice, and stress corrosion cracking, all while maintaining outstanding toughness, fatigue resistance, and dimensional stability even in challenging conditions.

To maintain Duplex Steel Flat Bars, regularly clean them to remove debris, inspect for corrosion, and apply protective coatings if necessary. Ensure proper storage to prevent exposure to harsh chemicals or extreme conditions.
Yes, Duplex Steel Flat Bars are suitable for natural gas applications due to their excellent corrosion resistance and strength, making them ideal for pipelines and equipment exposed to natural gas environments.
Duplex Steel Flat Bars are partially magnetic due to their ferritic phase. While not as magnetic as pure ferritic steels, they may exhibit some magnetic properties, especially in certain conditions.
Duplex Steel Flat Bars are widely utilized in industries that demand high strength, corrosion resistance, and durability. They are frequently found in chemical processing equipment, heat exchangers, pressure vessels, and piping systems. In the oil and gas sector, these flat bars are perfect for offshore platforms, valves, and structural components that face seawater and aggressive chemicals. Moreover, they are employed in marine engineering, desalination plants, pulp and paper industries, and power generation facilities. Their unique combination of mechanical strength, corrosion resistance, and reliability ensures they perform exceptionally well in critical 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.
