Additional information on stainless steel “rusting”:
304L and 316L stainless steel is non-porous, hygienic, rust-free and extremely durable. 300 Series
stainless steel contains both chromium and nickel. These elements create a passive film over the surface
of each crystalline structure of the metal once exposed to oxygen, which allows the metal to become
passive towards corrosion, or “stainless”. However, there are three general things that breakdown this
outer layer:
1) Mechanical Abrasion by using steel wool, wire brushes, scrapers, etc. These objects scratch the
surface of the stainless steel and leave behind traces of the “rustable” steel. – This can happen during
installation if ferrous metals are being used or worked on around the job site, or even the type of blade
that was used for any other metal.
2) Hard Water – water that is supplied varies in degrees of hardness from city to city. Hard water
contains many different minerals including iron deposits, magnesium, copper, etc. Hard water will leave
behind deposits which, when left to sit, will break down the passive layer.
3) Chlorides such as chlorine beach, sea water, salt water, table salt, etc.
If traces of ferrous steel are on the outside surface of stainless steel, these traces rust and form
discoloration, but this is not actually the stainless steel rusting
