Al Summan Metals, a well-regarded manufacturer and supplier based in Dubai, UAE, has earned a strong reputation for producing top-quality Duplex Steel Bright Bars that comply with international standards. With the help of advanced technology and stringent quality control practices, Al Summan Metals ensures that each bar delivers outstanding strength, durability, and corrosion resistance. The company caters to a wide range of industries, such as oil and gas, chemical processing, construction, and marine applications. Their Duplex Steel Bright Bars are available in various dimensions and finishes, offering clients tailored solutions for challenging environments where reliability and performance are essential.
These Duplex Steel Bright Bars consist mainly of chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), and nitrogen, producing an excellent equilibrium between austenitic and ferritic phases. This distinctive makeup provides them with exceptional mechanical strength, elevated yield and tensile strength, and impressive resistance to pitting and stress corrosion cracking. Featuring a tensile strength of roughly 620 MPa and a yield strength of nearly 450 MPa, these bars are engineered to endure high-pressure and high-temperature environments. Their well-balanced microstructure not only boosts toughness but also preserves formability throughout machining and fabrication.
