SS 317/317l plate grade has improved corrosion resistance over SS 304 Sheets and SS 316 Plates. Meanwhile, it has some great features like having an excellent Corrosion Resistance, Excellent Strength, Improved General and Localized Corrosion to SS 316.

Properties

Stainless Steel 317/317L sheets and plates are essentially non-magnetic in the annealed condition and can only be hardened by cold working. 317/317L Stainless Steel Sheets have restricted cobalt and tantalum content for nuclear applications.
