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 widely utilized in applications demanding superior strength and corrosion resistance. You’ll find them in pressure vessels, valves, shafts, pumps, flanges, and heat exchangers across marine, petrochemical, and offshore sectors. They shine in chloride-rich and acidic settings, such as seawater desalination systems and chemical processing plants. Thanks to their long-lasting durability, low maintenance needs, and resistance to localized corrosion, these forgings are the go-to choice for high-performance engineering and industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
