Product Description
Super Duplex Seamless Tube made from Super Duplex S32750 / 2507 material, manufactured to ASTM A789 / ASME SA789 standards. The tubes are produced through a seamless, cold drawn process with solution annealing and quenching. With a PREN > 40, these tubes are ideal for demanding applications in subsea, marine, desalination, and oil & gas industries.
Material Properties
Super Duplex steel S32750 is engineered for extreme performance in highly corrosive environments. Its unique chemical composition with high chromium, molybdenum, and nitrogen content delivers a Pitting Resistance Equivalent Number (PREN) exceeding 40, providing exceptional resistance to localized corrosion. In high-chloride environments like warm seawater, S32750 demonstrates remarkable immunity to stress corrosion cracking (SCC), outperforming standard duplex and most austenitic stainless steels.
Chemical & Mechanical Properties
Chemical Composition (wt %), ASTM A789:
- Chromium (Cr): 24.0 - 26.0
- Nickel (Ni): 6.0 - 8.0
- Molybdenum (Mo): 3.0 - 5.0
- Nitrogen (N): 0.24 - 0.32
- Manganese (Mn): 1.20 max
- Copper (Cu): 0.50 max
Mechanical Properties (Minimum), ASTM A789:
- Tensile Strength: 800 MPa (116 ksi)
- Yield Strength: 550 MPa (80 ksi)
- Elongation: 15%
- Hardness: 310 HBW / 32 HRC max
Marine Engineering Applications
S32750 Seamless Tube is the material of choice for critical marine applications including:
- Control lines and hydraulic pipes in subsea oil and gas production systems
- High-pressure process piping exposed to corrosive well fluids
- High-pressure components in seawater reverse osmosis (SWRO) desalination systems
- Offshore chemical plant equipment handling corrosive media
