SDSS Strips and Super Duplex Perforated Sheet supplier in India
NORSOK Super Duplex Plate supplier in India offer wide selection of 25cr SS Coils and SDSS Shim Stock at very genuine price
A SDSS grade is designed with equal proportions of austenitic and ferritic composition. The Super Duplex Plate is a fixture that is designed in thickness above 6mm and extends up to 150mm. These plates possess superior strength and provide stability to different applications in the system. A Super Duplex Stainless Steel Plate is designed with a superior chemical composition consisting of chromium, nickel, and molybdenum alongside other constituting alloys. This content gives the plates good corrosion and oxidation resistance properties. The Super Duplex Steel Plate has enhanced mechanical properties and showcases good tolerance against pitting and crevice corrosion across stress-induced conditions. A Super Duplex Sheet is an aesthetically appealing grade that is not employed to provide stability, but on the contrary, adds a glow to the grade. These grades are usually designed in sizes above 0.5mm, but below 6mm.
The Super Duplex Foil is one of the thinnest metal grades designed in thicknesses of less than 0.2mm. These foils protect the grade against damage during storage and heat treatment procedures. SDSS Strips are slightly thicker than foils and are available in thickness between 0.2mm to 0.5mm. These strips act as filler metal during different welding procedures. The Super Duplex Shim Stock is used to fill space between machinery and other parts to provide stability and support. These components are designed in different shapes and sizes as per requirements. SDSS Coil is wound soon after it is rolled. These coils are a massive fixture that can be efficiently transported and later sheared into plates, sheets, foil, and strips. They are quality assured and produced with the best raw materials using cutting-edge technology.

Finishes of Super Duplex Stainless Steel Plate
| Finish | Description |
|---|---|
| 2B | Reflective grey shine with a smooth finish. The most common type of surface finish. |
| Bright Annealed (BA) | Cold rolled and annealed in a controlled environment to keep a high-reflective finish. |
| Dull Polish (DP) | Used extensively in the catering business, as well as push and kick plates, for ease of cleaning, brushed look, non-reflective.. |
| Hot Rolled (HR) | Scaled finish, which is ideal if surface polish isn't a priority. |
