Stainless steel as an electrocatalyst for overall water …
However, since the exact structure and composition of the stainless steel catalyst after immersion in aqueous electrolyte are unknown, the surface should be treated as a mixture of metallic Fe and various oxide species. Metallic nickel also forms some form of oxide in the presence of alkaline solution [45].
Stainless Steel Ball Bearings
Unlike most ball transfers, which have metal balls, these have a plastic outer ball that rolls on stainless steel inner balls, so there's no metal-on-metal contact that could create and release particles into your clean room. They've also been ultrasonically cleaned and then individually bagged to prevent dust contamination.
