Al Summan Metals, a well-regarded manufacturer and supplier based in Dubai, UAE, is committed to producing premium Super Duplex Steel Bright Bars. These bars are renowned for their impressive strength, superior corrosion resistance, and excellent surface finish. Manufactured using advanced technology and accurate machining, they comply with international quality standards, making them ideal for demanding industrial environments. Owing to their distinctive dual-phase microstructure of austenite and ferrite, Super Duplex Steel Bright Bars offer strong protection against pitting, crevice corrosion, and chloride stress corrosion cracking, rendering them adaptable for a wide range of engineering and structural applications.
These bars consist of approximately 25% chromium, 7% nickel, and 3.6% molybdenum, along with added copper, tungsten, and nitrogen to enhance their strength and resistance to corrosion. They feature a tensile strength of roughly 800–850 MPa, a yield strength of 550 MPa, and an elongation of about 25%. The duplex structure ensures outstanding toughness, hardness, and fatigue resistance, even under extreme pressures and temperatures, providing lasting reliability and durability in tough industrial environments.

The hardness of Super Duplex Steel Bright Bars generally falls between 250-300 HB (Hardness Brinell), varying according to the particular grade and heat treatment, providing outstanding strength along with resistance to wear and corrosion.
Yes, Super Duplex Steel Bright Bars can be recycled once they have been used. Their elevated chromium and nickel content makes them extremely recyclable, supporting sustainability and lowering the demand for fresh raw materials.
Super Duplex Steel Bright Bars offer strong resistance to corrosion thanks to their elevated chromium and molybdenum levels. Nonetheless, in especially harsh conditions, extra coatings can be added for enhanced protection.
Al Summan Metals’ Super Duplex Steel Bright Bars are widely used across industries demanding both high mechanical strength and resistance to corrosion. They are especially suitable for marine engineering, offshore oil and gas platforms, desalination facilities, and chemical processing systems. Additionally, these bars are applied in heat exchangers, pumps, shafts, fasteners, and pressure vessels. Thanks to their excellent surface finish and accurate dimensions, they work well for both structural and decorative purposes. Their outstanding resistance to stress corrosion and pitting delivers reliable performance in harsh and high-temperature conditions.
We supply products accompanied by mill test certificates as well as third-party test certificates, guaranteeing the highest levels of quality and compliance.
