Semih Metals, located in Istanbul, Turkey, stands out as a top manufacturer and supplier of high-quality Super Duplex Steel S32750 Forgings. They cater to industries around the globe with precision-engineered solutions. Known for their exceptional durability and commitment to international standards, Semih Metals delivers forgings that offer remarkable strength, toughness, and resistance to corrosion. These Super Duplex Steel S32750 Forgings are specifically crafted to perform reliably in tough, high-pressure environments. With cutting-edge facilities and a focus on customer satisfaction, Semih Metals guarantees consistent quality, precise dimensions, and timely deliveries, making them a go-to partner for demanding industrial applications worldwide.
The Super Duplex Steel S32750 Forgings feature a unique dual-phase microstructure of ferrite and austenite, enriched with high levels of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen. This well-balanced chemical makeup provides outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-rich and acidic settings. On the mechanical side, these forgings boast a tensile strength of about 800–850 MPa, a yield strength of roughly 550 MPa, and impressive toughness, even in sub-zero temperatures. Their blend of high strength and excellent corrosion resistance ensures they remain reliable over the long haul in critical applications.

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 extensive use in sectors like oil and gas, chemical processing, marine, desalination, and power generation. They’re commonly used to create components such as flanges, valves, fittings, pump shafts, and pressure vessels that face exposure to seawater and harsh chemicals. Their ability to endure challenging operating conditions reduces maintenance needs and extends service life. Semih Metals’ Super Duplex Steel S32750 Forgings offer robust, corrosion-resistant, and cost-effective solutions for industries that require high-performance materials in demanding environments.
