Mourad Metals, located in Tunis, Tunisia, has built a solid reputation as a reliable manufacturer and supplier of top-notch Duplex Steel Rectangular Bars. The company focuses on crafting precision-engineered bars that adhere to international standards, catering to a diverse array of industrial sectors. Thanks to their advanced manufacturing techniques and rigorous quality control measures, Mourad Metals guarantees that each rectangular bar boasts consistent strength, durability, and impressive corrosion resistance. Their dedication to timely deliveries, technical know-how, and customer satisfaction has made them a go-to partner for engineers, fabricators, and industrial clients in need of high-quality Duplex Steel Rectangular Bars for demanding applications in the chemical, petrochemical, marine, and offshore industries.
These Duplex Steel Rectangular Bars are made up of around 22% chromium, 5–6% nickel, and 3% molybdenum, along with trace amounts of nitrogen and other alloying elements. This unique blend gives them outstanding mechanical properties, such as high tensile and yield strength, toughness, and ductility. Duplex steel is particularly known for its excellent resistance to 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 rectangular bars deliver remarkable performance in high-stress situations where durability and corrosion resistance are essential.

Duplex Steel Rectangular Bars can withstand moderate to high temperatures, but their performance may degrade at temperatures above 300°C (572°F). For extreme heat, other alloys like austenitic stainless steel are preferred.
Yes, Duplex Steel Rectangular Bar are highly recyclable. Their durable composition allows them to be melted down and repurposed in various applications without significant loss of material properties.
Duplex Steel Rectangular Bars have excellent natural corrosion resistance due to their alloy composition. However, in highly aggressive environments, additional coatings or treatments may be recommended for enhanced protection.
You’ll find Duplex Steel Rectangular Bars commonly used across the chemical, petrochemical, marine, and desalination sectors, thanks to their impressive mechanical strength and corrosion resistance. They’re perfect for creating structural components, pressure vessels, heat exchangers, piping systems, pumps, and valves that face harsh chemicals or high-pressure conditions. Moreover, they’re well-suited for offshore platforms, chemical reactors, and seawater systems, where a long service life and dependable performance 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.
