EN 1.4162 / LEAN DUPLEX UNS S32101 / LDX 2101

• Applications

  The main applications are for details with corrosion resistance and/or higher strength demands than 304L / 316L.

  Structural Components

  • • Bridges, walkways, and architectural structures
    • Offshore platforms and marine environments (due to good chloride resistance)

  Process Industry

  • • Chemical and petrochemical equipment
    • Pulp and paper industry components
    • Storage tanks and pressure vessels

  Water Systems

  • • Desalination plants
    • Water treatment facilities
    • Heat exchangers and piping systems

  Transportation

  • • Cargo tanks for trucks and ships
    • Rail tankers for chemicals

  Construction

  • • Reinforcement bars in concrete (especially in aggressive environments)
    • Building facades and roofing

   

• Heat Treatment and Weldability

  Solution annealing at 1020 – 1100°C followed by water quenching.

  Weldability: Very good
