316LS is a Stainless Steel grade that is vacuum arc remelted in order to maximize corrosion resistance and provide a ferrite free micro structure.
Strip, Coil, Foil & Wire, ASTM F138, ASTM F139, ISO 5832
Description
316LS is a Stainless Steel grade that is vacuum arc remelted in order to maximize corrosion resistance and provide a ferrite free micro structure. This version of 316 Stainless Steel contains higher nickel, lower carbon, lower molybdenum and lower chromium content than standard 316L. It is often dual certified and referred to as 316LVM Stainless Steel, in which the VM stands for vacuum melt. 316LS is often used for implants as well as other surgical applications due to its' properties.

Finishes for 316LS
| #1 | Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required. |
| #2D | Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process. |
| #2B | Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D. |
| #BA | Bright annealed cold rolled and bright annealed |
| #CBA | Course bright annealed cold rolled matte finish and bright anneal |
| #2 | Cold Rolled |
| #2BA | Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part. |
| Polished | Various grit finish for specific polish finished requirements. |
