Khaleed Stainless, located in Riyadh, Saudi Arabia, has earned a solid reputation as a reliable manufacturer and supplier of top-notch stainless and special alloy products. One of their standout offerings is **Super Duplex Steel Forgings**, crafted to withstand the toughest challenges in heavy-duty and corrosive environments. These forgings are celebrated for their remarkable strength, toughness, and resistance to corrosion, particularly in chloride-rich and marine conditions. With a commitment to precision engineering and customer satisfaction, Khaleed Stainless delivers forged components that are essential for critical applications in the oil & gas, petrochemical, marine, and power generation sectors, ensuring they perform reliably and last long even in harsh operating conditions.
Super Duplex Steel Forgings are primarily produced from grades like UNS S32750 and S32760, which boast a blend of high chromium (around 25%), molybdenum (about 4%), and nickel (approximately 7%). This unique composition grants them outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, they provide impressive tensile strength (typically ranging from 750 to 900 MPa) and yield strength (around 550 MPa), along with good impact toughness, even in colder temperatures. The duplex structure, which combines austenite and ferrite phases, ensures both mechanical durability and corrosion protection, making these forgings perfect for demanding environments.

To verify the quality of Super Duplex Steel forgings, check for certifications like ASTM, ASME, or ISO standards. Conduct tests such as mechanical property testing, chemical composition analysis, and non-destructive testing (NDT) like ultrasonic or magnetic particle inspections.
Compatible welding processes for Super Duplex Steel forgings include Tungsten Inert Gas (TIG), Metal Inert Gas (MIG), Shielded Metal Arc Welding (SMAW), and Submerged Arc Welding (SAW), using appropriate filler materials.
Super Duplex Steel forgings are governed by standards such as ASTM A182, ASTM A240, ASME SA-182, ASME SA-240, and EN 10088-3, which define material properties, chemical composition, and mechanical requirements.
Super Duplex Steel Forgings find their place in industries where mechanical strength and corrosion resistance are paramount. In the oil and gas sector, they are ideal for subsea equipment, valves, flanges, and manifolds that face exposure to seawater and harsh chemicals. In chemical processing, they serve as vital components for reactor vessels and heat exchangers. Marine applications depend on them for propeller shafts and rudder parts. Power and desalination plants utilize them for structural components that endure high pressure and aggressive fluids. Their durability significantly cuts down on maintenance needs, making them a smart choice for any demanding application.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
