Al Summan Metals, headquartered in Dubai, UAE, has built a strong name for itself as a dependable manufacturer and supplier of high-quality stainless steel products, with a special emphasis on Duplex Steel Forgings. Drawing on extensive expertise in precision manufacturing and advanced metallurgy, Al Summan Metals offers durable and corrosion-resistant forged components fit for a broad spectrum of industrial applications. Duplex Steel Forgings distinctively combine the strength of ferritic and austenitic stainless steels, providing exceptional mechanical performance and durability in demanding conditions. Committed to maintaining international quality benchmarks, dependability, and customer satisfaction, Al Summan Metals caters to a variety of industries, including oil and gas, chemical processing, marine, construction, and power generation, both within UAE and across the world.
These Duplex Steel Forgings generally contain around 22% chromium, 5% nickel, 3% molybdenum, plus small quantities of nitrogen, manganese, and silicon. This carefully balanced makeup gives them outstanding corrosion resistance and notable mechanical strength. The material offers a yield strength between 450 and 550 MPa and a tensile strength ranging from 620 to 850 MPa, with hardness typically sitting between 280 and 330 HB. Its distinctive dual-phase microstructure—made up of nearly equal proportions of ferrite and austenite—delivers exceptional toughness, fatigue resistance, and dimensional stability, even when subjected to extreme pressure and temperature.

Confirm duplex steel forgings' quality by reviewing certifications, such as ASTM or ISO standards, performing material testing (e.g., tensile, hardness, corrosion resistance), and examining for uniform dimensions, surface finish, and correct labeling.
Duplex steel forgings are highly resistant to corrosion thanks to their distinctive combination of austenitic and ferritic microstructures, which deliver outstanding protection against pitting, crevice corrosion, and stress corrosion cracking.
Duplex steel forgings generally have a maximum operating temperature between 250°C and 300°C (482°F to 572°F), varying according to the particular grade and use case, in order to preserve ideal mechanical properties.
Duplex Steel Forgings are widely used across industries that require exceptional strength, durability, and resistance to corrosion. They are ideal for producing parts such as flanges, shafts, rings, and valve bodies in fields like oil and gas, petrochemical, marine, and desalination. These forgings perform outstandingly in chloride-heavy or acidic conditions, greatly reducing the risk of pitting and stress corrosion cracking. In addition, they serve in heat exchangers, pressure vessels, and structural uses where high mechanical performance is essential. With Duplex Steel Forgings, you can rely on enduring dependability, reduced maintenance requirements, and cost efficiency in demanding industrial operations.
We supply materials accompanied by mill test certificates as well as third-party test certificates, guaranteeing the highest levels of quality and compliance.
