Rashid Metals stands out as a top manufacturer and supplier of high-quality Duplex Steel Flat Bars in Muscat, Oman. With state-of-the-art production facilities and rigorous quality control measures, we ensure our products meet international standards and the high demands of today’s industries. Our Duplex Steel Flat Bars are known for their exceptional strength, resistance to corrosion, and precise dimensions, making them perfect for tough environments. Trusted throughout the Middle East and beyond, Rashid Metals guarantees reliable performance, longevity, and consistent quality for engineering, chemical, and offshore applications where durability and safety are paramount.
Duplex Steel Flat Bars are crafted from a well-balanced blend of austenitic and ferritic stainless steel, primarily featuring chromium, nickel, and molybdenum. This unique composition offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, duplex flat bars boast high tensile and yield strength—almost double that of standard austenitic stainless steel—while also providing good ductility and impact toughness. They maintain their structural stability and mechanical integrity even under high pressure, fluctuating temperatures, and harsh chemical 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 find extensive use in industries that demand both strength and corrosion resistance. You’ll commonly see them in offshore and marine structures, chemical processing equipment, heat exchangers, and pressure vessels. They’re also utilized in desalination plants, the pulp and paper industry, and oil and gas pipelines, thanks to their ability to resist chloride-induced corrosion and stress cracking. These flat bars are perfect for creating structural supports, frames, fasteners, and machined components that require long-lasting durability, reliability, and safety in challenging conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
