Super Duplex Steel 2507 - UNS S32750 Pipe - Tube


 We manufacture, export & supply Super Duplex S32750 Welded Pipe. We also produce various Welded, ERW, EFW and Fabricated types with excellent quality but lower costs in square, rectangular, spiral, u-shape, and hydraulic forms. Super Duplex UNS S32750 is an austenitic-ferritic Duplex steel that provides excellent resistance to pitting corrosion & crevice corrosion.

 UNS S32750, more popular as Super Duplex Steel 2507, is widely used in applications requiring top-level corrosion protection and robustness. It is a type of Duplex stainless steel composed of chromium, molybdenum, nickel, and other alloying components to enhance its corrosion and erosion-resistant properties. UNS S32750 Super Duplex Pipes exhibits remarkable fatigue strength, allowing it to handle repetitive strain cycles without succumbing to wear and tear. This renders it suitable for usage in projects involving consistent loading, such as building bridges, aeroplanes, and other infrastructures. UNS S32750 Super Duplex also has the distinct advantage of possessing remarkable strength. With a remarkable tensile strength of around 800 MPa, it is much stronger than other stainless steel varieties. This makes it the perfect choice for applications where robust strength is an absolute must. This material is excellent for welding and forming, making it easily adaptable to various shapes and sizes.  Additionally, Super Duplex Steel 2507 displays superb resistance to corrosion from various organic acids and other chemical substances. Consequently, it is widely employed in the chemical processing industry, characterized by intense heat and dangerous substances. Moreover, the material has a low coefficient of thermal expansion, which implies that it barely increases or reduces in size when exposed to variations in temperature. Consequently, it is ideal for use in activities where consistent dimensions are essential, such as precise engineering.

Super Duplex 2507 Pipes, Super Duplex Hexagonal Pipes tube in Pune UNS S32750 Hallow Pipes tube in Saudi Arabia, Alloy 2304 Hexagonal Pipes tube in Egypt, ASTM A790 Super Duplex UNS S32750 Bush Hex Pipes tube Supplier in Mumbai, India.

Our ASTM 790 Super Duplex Steel Welded Pipes are multi-purpose and possess good weldability, used widely in the offshore and marine industry for their acid corrosion resistance. ASTM A790 Super Duplex Steel UNS S32750 Pipes are highly alloyed with different metals and have greater mechanical strength. These pipes have a high chloride corrosion resistance, suitable for chloride-aggressive operations.

 We manufacture, export & supply UNS S32750 Super Duplex Steel Tubes to spheres of industries ranging from basic industries such as Sugar, Paper, Textile, and Engineering to more complex such as Oil & Gas, Petrochemical, Chemical & Fertilizers, Power Generation and Nuclear Industries. Super Duplex Stainless steels, which combine high strength and excellent corrosion resistance in many environments, have found applications in chemical and process industries. Pulp mills, offshore systems, flue gas desulphurization units. The localized corrosion resistance of Super-Duplex Steels is close to what is achieved with 6% Mo Super-Austenitic grades. Our company pays close attention when packing UNS S32750 pipes and tubes to guarantee the best possible condition upon delivery to our customers. We source top-quality packaging materials that are strong, long-lasting, and can endure hurting in transit. Each pipe and tube is counselled and shrouded in a protective covering to prevent scratches or other damage. Durable wooden crates and pallets are then used to provide secure packaging for the pipes and tubes. Our team is particularly cautious about packing the pipes and tubes to ensure they remain stable and that no shifting occurs during transportation, which lessens the likelihood of damage.

Super Duplex Steel S32750 Pipe Mechanical Properties :

  • Super Duplex stainless steels exhibit PREN value higher than 40.
  • Combines most desirable characteristics of both super-ferritic and Super-Austenitic steel.
  • Has excellent resistance to chloride SCC, pitting, crevice and general corrosion and carbide related inter-granular corrosion.
  • Possesses high strength & impact strength.
  • Has high thermal conductivity and a lower coefficient of thermal expansion compared to Super Austenitic steels.

FABRICABILITY :

  • It should be hot worked in the range of 1250-1000 deg C, followed by a solution annealing at 1100 deg C and rapid quench.
  • It can be cold formed using methods similar to those commonly used for Stainless Steel. The primary difference is that the high yield strength makes it necessary to have higher forming forces, increased radius of bending, and increased allowance for spring back.
  • Deep drawing, stretch forming and similar processes are difficult to perform.

WELDABILITY :

  • It possesses good weldability and can be welded to itself and other materials by Shielded Metal Arc Welding (SMAW), GasTungsten Arc Welding (GTAW), Plasma Arc Welding (PAW) or Submerged Arc Welding (SAW).
  • Surfaces must be clean before welding.
  • Preheating is not necessary, except to prevent condensation on cold metal.
  • The recommended heat input should be nearly about 0.3-1.5K1/mm.
  • The interpass temperature should not exceed 150 deg C.
  • The root should be shielded with commercial Ar or 90%N2 / 10%H2 purging gas for maximum corrosion resistance.

CORROSION RESISTANCE :

  • It is highly resistant to carbide related inter-granular corrosion due to its low carbon content which lowers .
  • The risk of carbide precipitation at the grain boundaries during heat treatment. Its critical pitting temperature (CPT) is superior to that of 904L.
  • It has excellent resistance to crevice corrosion and SCC.
  • Extremely resistant to uniform corrosion by organic acids such as formic and acetic acid and also to inorganic acids, especially those containing chlorides.
  • Excellent corrosion resistance against highly corrosive acids like Sulphuric, Nitric, Phosphoric acids.
