Super Duplex (2507 Stainless Steel) is the true marine grade stainless as it is 100% corrosion resistant in salt water (it has a minimum PREN value of 41) and can withstand even the harshest environments. These make them the best coastal fasteners around!
Advantages
- Can be specified for sea water piling applications in H6 timber
- High strength (800 – 1000 MPa tensile strength)
- Extreme corrosion resistance and has a minimum PREN Value of 41, far higher than 316 Stainless Steel
- Ideal for coastal construction such as piers, sea walls and pilings/footings
- Other Super Duplex 2507 Stainless items can be made to order
Installation
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
