Al Summan Metals, a well-regarded manufacturer and supplier based in Dubai, UAE, specializes in producing high-quality Super Duplex Steel Square Bars. These bars are renowned for their remarkable strength, corrosion resistance, and enduring durability. Every bar is carefully engineered using advanced manufacturing methods, complying with international quality standards. Thanks to a balanced austenitic-ferritic microstructure, these Super Duplex Steel Square Bars perform exceptionally well against pitting, crevice corrosion, and chloride stress corrosion cracking. Al Summan Metals provides these bars for essential industrial uses across multiple sectors, such as oil and gas, chemical processing, marine engineering, and power generation, guaranteeing dependable performance over the long term.
These Super Duplex Steel Square Bars consist of approximately 25% chromium, 7% nickel, 3.6% molybdenum, together with small quantities of copper, tungsten, and nitrogen, which collectively deliver exceptional resistance to corrosion and oxidation. They exhibit remarkable mechanical properties, with a tensile strength of 800–850 MPa, a yield strength of 550 MPa, and an elongation of around 25%. The duplex microstructure not only improves their hardness and toughness but also increases their fatigue resistance, allowing them to perform well under high pressure, temperature, and demanding environmental conditions.
