Chung Metal, Da Nang, provides Super Duplex Steel S32750 Bars and Rods, designed to possess high strength with outstanding corrosion resistance. The material brings together both ferritic and austenitic phases of microstructure (“duplex”) to provide outstanding performance compared to traditional stainless steels when subjected to stress, temperature, and corrosive service. Our S32750 rods/bars are solution treated and subsequent finer machining or cold working as necessary to attain close tolerances, good surface finish, and stable mechanical performance. They find extensive application in marine, oil & gas, chemical process, and offshore environments where corrosion resistance and resistance to chloride stress corrosion are of prime importance.
S32750 contains about 24‑26% chromium, 3‑5% molybdenum, 6‑8% nickel, approximately 0.2‑0.3% nitrogen, trace amounts of carbon (<0.03%), and balance iron, with trace amounts of manganese, silicon, phosphorus, and sulfur. Density is about 7.8 g/cm³. Mechanical properties are generally a 0.2% yield strength of around 550‑600 MPa, tensile strength of around 800‑850 MPa, elongation ~15‑25% depending on section thickness, and excellent toughness even at low temperature. It possesses high hardness among stainless steels, good weldability, and excellent strength retention at high temperatures.

Yes, Super Duplex Steel S32750 Bars are highly corrosion-resistant, offering excellent protection against pitting, crevice corrosion, and stress corrosion cracking. They are ideal for harsh environments, including marine and chemical industries.
Yes, Super Duplex Steel S32750 Bars can be used for underground applications due to their excellent corrosion resistance, high strength, and durability in harsh environments. Their resistance to stress corrosion cracking makes them suitable for such conditions.
Super Duplex Steel S32750 Bars offer exceptional corrosion resistance, high strength, and excellent toughness. They are ideal for harsh environments, resisting pitting, crevice corrosion, and stress corrosion cracking.
The Super Duplex S32750 bars/rods are used in applications like subsea hardware, offshore oil & gas platforms, risers, valves, pump components, heat exchangers, and chemical process plant equipment facing chlorides. They are suitable for seawater piping, fire‑water systems, desalination, and marine structural parts. In chemical facilities, they are utilized in corrosive liquid conditions, acid service, or where crevice or pitting corrosion is at issue. Their high strength enables lighter, thinner parts than regular steel, saving weight and expense without compromising safety.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
