Mourad Metals, located in Tunis, Tunisia, stands out as a top manufacturer and supplier of high-quality Duplex Steel Hex Bars. The company is dedicated to crafting precision-engineered hex bars that adhere to international standards, serving a wide range of industrial needs. By employing cutting-edge manufacturing techniques and maintaining rigorous quality control, Mourad Metals guarantees that each hex bar offers consistent strength, durability, and impressive corrosion resistance. With a strong commitment to timely deliveries, technical support, and customer satisfaction, the company has built a solid reputation as a trusted partner for engineers, fabricators, and industrial clients in search of top-notch Duplex Steel Hex Bars for challenging environments in the chemical, petrochemical, marine, and offshore sectors.
Duplex Steel Hex Bars are made up of approximately 22% chromium, 5–6% nickel, and 3% molybdenum, along with trace amounts of nitrogen and other alloying elements. This unique composition endows the steel with remarkable mechanical properties, such as high tensile and yield strength, toughness, and ductility. Duplex steel excels in resisting pitting, stress corrosion cracking, and general corrosion, especially in environments rich in chlorides and aggressive chemicals. By merging the advantages of austenitic and ferritic stainless steels, these hex bars ensure reliability and structural integrity even under high stress, temperature fluctuations, and harsh chemical conditions.

Yes, Duplex Steel Hex Bars are fully recyclable. They can be melted down and reused without losing their essential properties, making them an environmentally sustainable option for various applications.
Duplex Steel Hex Bars have inherent corrosion resistance due to their composition. However, in highly aggressive environments, additional coatings or treatments may be necessary to enhance their longevity and performance.
To choose the right Duplex Steel Hex Bar, consider factors such as mechanical strength, corrosion resistance, temperature conditions, and compatibility with your application’s specific industry standards and environmental factors.
These Duplex Steel Hex Bars find extensive applications in the chemical, petrochemical, marine, oil and gas, and desalination industries, thanks to their exceptional strength and corrosion resistance. They are frequently used in the manufacturing of pumps, valves, fasteners, structural components, heat exchangers, and piping systems that are exposed to harsh chemicals or high-pressure situations. Moreover, these hex bars are ideal for offshore platforms, chemical reactors, and seawater systems where durability is crucial.
