Khaleed Stainless, located in Riyadh, Saudi Arabia, is a reputable manufacturer and supplier of high-quality stainless steel and alloy products. One of their standout offerings is the **Super Duplex Steel S32750 Forgings**, crafted to withstand extreme mechanical stress and harsh corrosive environments. These forgings are a perfect blend of high strength and remarkable corrosion resistance, making them a go-to choice for demanding applications in offshore, petrochemical, and chemical processing sectors. With a strong commitment to quality, precision, and adherence to international standards, Khaleed Stainless ensures that their S32750 forgings meet stringent operational requirements while providing durability, safety, and a long service life.
Super Duplex Steel S32750 is a high-alloy duplex stainless steel that features around 25% chromium, 7% nickel, 4% molybdenum, and nitrogen. This well-balanced dual-phase (ferritic-austenitic) structure offers exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. The material boasts a high tensile strength ranging from 750 to 930 MPa and a yield strength of about 550 MPa. Additionally, S32750 retains impressive impact toughness even in sub-zero temperatures. These mechanical properties, paired with outstanding corrosion resistance, make it an excellent choice for components that face high pressure, aggressive chemicals, and seawater.

Yes, S32750 super duplex steel forgings are ideal for offshore and marine applications due to their excellent corrosion resistance, high strength, and resistance to pitting, crevice corrosion, and stress corrosion cracking.
Super Duplex Steel S32750 forgings are compatible with welding processes like GTAW (TIG), SMAW (Stick), GMAW (MIG), and SAW, using matching filler metals to ensure corrosion resistance and strength.
Limitations of S32750 forgings include susceptibility to hydrogen embrittlement, limited high-temperature performance, potential for welding-induced phase imbalance, and careful heat treatment requirements to maintain corrosion resistance and mechanical properties.
Super Duplex Steel S32750 Forgings find their place in critical applications where both strength and corrosion resistance are vital. In the oil and gas sector, they are perfect for subsea and topside components such as flanges, valves, shafts, and connectors. In chemical processing facilities, they are utilized in reactors, pumps, and pressure vessels that deal with aggressive fluids. Marine and desalination systems rely on them for their long-lasting resistance to saltwater and biofouling. Their high performance in tough conditions minimizes maintenance needs, enhances system reliability, and ultimately contributes to a more efficient operation.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
