Duplex Stainless SteelsISSF DUPLEX STAINLESS STEELS 2BACK_ ? __ Foreword The first experiments making duplex stainless steels were initiated in the early 1930s with Avesta AB in Sweden playing a significant role in this development. As we now approach the 90th anniversary of the development of duplex grades, it gives me great pleasure to provide the foreword for the ISSFs new brochure on this family of stainless steels. This brochure is an extremely useful reference document

How to fill out duplex stainless steels

How to fill out duplex stainless steels

1. Begin by gathering all necessary materials and tools: duplex stainless steel sheet, cutting tools, welding equipment, and safety gear.
2. Ensure the work area is clean and free of contaminants that could affect the integrity of the duplex stainless steel.
3. Cut the duplex stainless steel to the required dimensions using appropriate cutting tools.
4. Clean the edges of the cut pieces to remove any burrs or oxidation, ensuring a good fit for welding or assembly.
5. Align the pieces accurately as per the design specifications, using clamps or fixtures to hold them in place.
6. Proceed with welding the pieces together using a suitable welding method that is compatible with duplex stainless steel.
7. After welding, perform a visual inspection and any necessary non-destructive testing to ensure weld quality.
8. Finish the assembly by grinding or polishing surfaces as needed, and apply any protective coatings if required.
