Aiman Metals stands out as a top manufacturer and supplier of Super Duplex Steel S32750 Forgings right in the heart of Kuala Lumpur, Malaysia. They pride themselves on delivering high-quality products that align with international standards. These forgings are celebrated for their remarkable strength, resistance to corrosion, and long-lasting durability, making them perfect for tough environments and demanding applications. Aiman Metals is dedicated to precision engineering, consistent quality, and timely delivery, catering to a wide range of industrial needs. With state-of-the-art manufacturing facilities and a strong focus on customer satisfaction, they serve various sectors, including oil and gas, petrochemicals, marine, and power generation, earning a solid reputation in the metal forging industry.
Super Duplex Steel S32750 Forgings are made up of about 25% chromium, 7% nickel, and 4% molybdenum, along with nitrogen and trace elements that boost their corrosion resistance. They boast a high tensile strength of around 800 MPa and a yield strength of 550 MPa, along with excellent toughness, even in low temperatures. Thanks to their balanced austenitic-ferritic microstructure, these forgings excel in resisting pitting, crevice corrosion, and chloride stress corrosion cracking, making them ideal for critical industrial applications that demand superior mechanical performance and durability.

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.
These Super Duplex Steel S32750 Forgings find their place in industries where high strength and corrosion resistance are non-negotiable. You’ll commonly see them in offshore oil and gas platforms, subsea equipment, desalination plants, chemical processing units, and pressure vessels. They’re also a go-to choice in marine engineering, heat exchangers, and the pulp and paper industries, thanks to their ability to handle aggressive chemical environments. Their blend of durability, excellent weldability, and resistance to both localized and general corrosion makes them the preferred option for components operating in highly corrosive or high-pressure settings, ensuring they deliver reliable performance for 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.
