321

The chemical composition for Stainless Steel 321 blind flanges is: Carbon (C) 0.08%, Manganese (Mn) 2%, Phosphorus (P) 0.045%, Silicon (Si) 0.75%, Nickel (Ni) 9-12%, Sulfur (S) 0.030%, Iron (Fe) balance%. This composition provides excellent corrosion resistance and high-temperature strength, allowing it to be machined easily compared with other stainless steel grades.

321 SS blind flanges are most often used in industrial applications, where their excellent corrosion resistance and high-temperature strength make them a great choice. These properties also make this material ideal for chemical, petrochemical, pulp, and paper industries and food and pharmaceutical production. The material's machinability allows for precision cutting and forming with minimal stress on the metal. This makes it suitable for both small-scale operations and large production runs. Additionally, its low carbon content gives it good weldability with other stainless steel grades while providing excellent corrosion resistance.
