Mourad Metals, located in Tunis, Tunisia, stands out as a top-notch manufacturer and supplier of high-quality Duplex Steel Forgings. The company is dedicated to crafting precision-engineered forgings that adhere to international standards, catering to a variety of industrial sectors. By leveraging cutting-edge forging technology and maintaining rigorous quality control, Mourad Metals guarantees that each forging boasts consistent strength, durability, and impressive corrosion resistance. With a strong commitment to timely deliveries, technical know-how, and customer satisfaction, the company has earned a reputation as a reliable partner for engineers, fabricators, and industrial clients in need of dependable Duplex Steel Forgings for challenging applications in chemical processing, petrochemical, marine, and offshore settings.
Duplex Steel Forgings 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 blend gives the steel remarkable mechanical properties, such as high tensile and yield strength, toughness, and ductility. Duplex steel is known for its exceptional resistance to pitting, stress corrosion cracking, and general corrosion, especially in harsh and chloride-rich environments. By combining the best features of both austenitic and ferritic stainless steels, these forgings maintain their structural integrity and performance even under high stress, temperature fluctuations, and aggressive chemical 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 find extensive applications in the chemical, petrochemical, oil and gas, marine, and desalination industries, thanks to their outstanding mechanical strength and corrosion resistance. They are frequently used in the production of valves, pumps, piping systems, pressure vessels, and heat exchangers that are exposed to harsh chemicals or high-pressure situations. Moreover, these forgings are ideal for offshore platforms, seawater systems, and chemical reactors, where both durability and corrosion resistance are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
