Tariku Metals, located in Addis Ababa, Ethiopia, has made a name for itself as a top-notch manufacturer and supplier of high-quality Super Duplex Steel S32750 Forgings. The company is committed to delivering forged products that not only meet but exceed international standards for strength, corrosion resistance, and reliability. By leveraging cutting-edge production technologies and maintaining rigorous quality control processes, Tariku Metals guarantees exceptional mechanical properties and precise dimensions in every forging. With a solid reputation for excellence in sectors like oil and gas, chemical processing, marine engineering, and power generation, Tariku Metals provides durable, high-performance materials that are ready to tackle the toughest industrial challenges around the globe.
Super Duplex Steel S32750 Forgings from Tariku Metals are crafted with about 25% chromium, 7% nickel, 4% molybdenum, and some nitrogen, which together deliver remarkable strength and resistance to pitting, crevice, and stress corrosion cracking. They feature a dual-phase microstructure (austenitic-ferritic) that guarantees top-notch mechanical performance. Typically, you can expect mechanical properties like a tensile strength of around 800 MPa, a yield strength of 550 MPa, and an elongation of 25%. These forgings not only offer high strength but also excellent toughness, ensuring they can withstand corrosion even in tough, chloride-rich marine environments.

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 are a go-to choice in industries that require top-notch corrosion resistance and strength. In the oil and gas world, you’ll find them in subsea equipment, pressure vessels, flanges, and valve components. The chemical processing and desalination sectors depend on these forgings for heat exchangers, pumps, and piping systems that face harsh chemicals and seawater. In marine and offshore engineering, they shine by offering durability in extremely salty environments. Plus, they’re also essential in power generation and the pulp and paper industries, where being resistant to fatigue and stress corrosion is crucial for keeping operations running smoothly over the long haul.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
