Strength of Haiwo 2507 Duplex Stainless Steel Coil:

• 
  

  Exceptional chloride resistance: Higher PREN value than 2205, resists severe pitting, crevice and stress corrosion in deep seawater

• Ultra-high mechanical strength: Much higher yield strength than austenitic stainless grades, reduces structural thickness and overall engineering costs

• Stable performance under high pressure & moderate high temperature, reliable for long-term subsea operation

• Good weldability and formability, compatible with professional duplex welding consumables for site fabrication

• Superior sulfide stress cracking resistance, fit for sour oil & gas working conditions

• Extended service lifespan cuts maintenance and replacement costs for large capital projects

  
  

Main Application of 2507 Duplex Stainless Steel Coil:

• 
  

  Deep sea & offshore engineering: Subsea device shells, offshore platform structural components, seawater intake pipelines

• High-end petrochemical & chemical industry: Corrosive medium reactors, high-pressure storage vessels, acid processing equipment

• Desalination mega plants: High-salinity brine processing equipment, ultra-large seawater conveying systems

• Oil & gas sour fields: Sour gas pipeline liners, high-pressure downhole auxiliary components
