Stainless steel and corrosive influences
Rust-proof stainless steel is a product designation for a
group of particularly corrosion-resistant and hygienic
steels.
The corrosion resistance is based on an invisible passive layer,
which is formed by the entry of oxygen in the air and which heals
itself if injured.
If this passive layer is injured (e.g. through soiling), this may result in
corrosion.
The following chapters contain information on how you can keep the
risk of corrosion as small as possible.
