With a focus on high-performance metals, Hemi Metals guarantees that each forging adheres to rigorous quality standards, providing dependable and long-lasting solutions for challenging industrial applications. Their S32750 forgings are perfect for manufacturers, engineers, and fabricators who need materials that can endure harsh chemical, thermal, and mechanical conditions. Offering technical support, tailored solutions, and prompt delivery, Hemi Metals has built a reputation as a reliable partner for industrial and offshore projects both in New Zealand and around the globe.
Super Duplex Steel S32750 Forgings are high-alloy duplex stainless steels that contain about 25% chromium, 7% nickel, 4% molybdenum, and 0.3% nitrogen. This unique chemical makeup gives them outstanding resistance to pitting, crevice, and stress corrosion cracking, especially in environments rich in chlorides and harsh chemicals. On the mechanical side, S32750 boasts a tensile strength ranging from 900 to 1100 MPa, a yield strength of 700 to 900 MPa, and a hardness of approximately 320 to 350 HB. The blend of high strength, excellent toughness, and superior corrosion resistance makes these forgings perfect for critical applications that demand long-lasting durability and reliability.

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 the oil and gas, chemical processing, desalination, offshore, and marine sectors. They are commonly used in valves, flanges, pump components, pressure vessels, and structural parts that are exposed to tough and corrosive environments. Their exceptional mechanical strength and resistance to chloride-induced stress corrosion make them ideal for critical applications where reliability, safety, and longevity are absolutely essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
