*Guidelines

To maintain 100% corrosion resistance to saltwater, please follow the below guidelines when working/handling Super Duplex (2507 SS).

  • Only use tools that have been exclusively used on SS material to avoid cross contamination of carbon steel onto Super Duplex (2507 SS)
  • If Super Duplex (2507 SS) fasteners are worked with high temperature processes such as welding, annealing or cutting with cutting discs, use a pickle/passivating paste on the affected area to reduce the corrosion caused by heating
