Austenitic 316 L stainless steel resists corrosion but under certain conditions :
- Be as bright as possible, hence a polishing or brightening operation.
- Have been stripped and passivated after arc welding.
Chemical brightening of stainless steels :
Chemical treatment that makes it possible to brighten austenitic stainless steels and nickel-based steels (inconel, monel, hastelloy..).

- BONDERITE C-IC 18010 Pâte
Pickling and passivation of stainless steels:
Stainless steel has a high corrosion resistance thanks to the non-transparent chromium oxide film developed on its surface.
The welding of stainless steel causes a layer of iron oxides during surface heating. The locally applied red weld transforms the crystalline structure and the composition of this passive oxide skin, it forms a porous layer of iron oxides that colors the surface.
Stainless steel during various deburring, grinding or machining operations may be contaminated with ferrous particles from the equipment used.
