Al Summan Metals, headquartered in Dubai, UAE, has earned a strong standing as a dependable manufacturer and supplier of premium stainless steel products, with special emphasis on Duplex Steel Rectangular Bars. Recognized for their precise engineering and superior materials, Al Summan Metals offers long-lasting, corrosion-resistant solutions that comply with international standards. These Duplex Steel Rectangular Bars skillfully combine the benefits of both ferritic and austenitic stainless steels, providing exceptional mechanical strength, toughness, and remarkable resistance to pitting and stress corrosion. Dedicated to guaranteeing customer satisfaction, dependability, and timely delivery, Al Summan Metals serves vital industries such as oil and gas, marine, construction, and chemical processing across UAE and beyond.
The Duplex Steel Rectangular Bars are generally made up of roughly 22% chromium, 5% nickel, and 3% molybdenum, together with minor quantities of nitrogen, manganese, and silicon. This carefully balanced blend forms a two-phase microstructure of ferrite and austenite, ensuring outstanding corrosion resistance and superior strength. Such bars feature a yield strength of 450 to 550 MPa and a tensile strength spanning 620 to 850 MPa, along with a hardness rating of roughly 280 to 330 HB. They further deliver remarkable toughness, fatigue resistance, and dimensional stability, which makes them ideal for uses demanding durability under harsh conditions.

Duplex Steel Rectangular Bars can handle moderate to high temperatures, though their performance may decline at temperatures exceeding 300°C (572°F). In cases of extreme heat, other alloys such as austenitic stainless steel are the better choice.
Yes, Duplex Steel Rectangular Bar are highly recyclable. Their durable makeup means they can be melted down and reused across a range of applications without meaningful loss of material properties.
Duplex Steel Rectangular Bars offer outstanding inherent resistance to corrosion thanks to their alloy makeup. Nevertheless, in extremely harsh conditions, supplementary coatings or treatments might be advised for improved protection.
Duplex Steel Rectangular Bars are well-suited to industries that require both high strength and resistance to corrosion. Typical uses cover structural frameworks, support beams, chemical processing equipment, pressure vessels, and marine components. These bars perform exceptionally well in settings containing chlorides and acids, successfully withstanding pitting, crevice corrosion, and stress corrosion cracking. They also serve in oil and gas pipelines, desalination plants, and offshore platforms. Thanks to their durable performance, lower maintenance requirements, and cost effectiveness, Duplex Steel Rectangular Bars remain a preferred option for demanding industrial applications.
We provide items that come with both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
