Factors That Can Cause Stainless Steel To Corrode:Unaccounted-for Environmental Factors
There are many cases where a manufacturer can make a custom stainless steel wire basket or tray perfectly to specification, only for it to corrode because of some previously unaccounted-for environmental factor. The presence of salt and moisture in the air because of a factory’s coastal location is one example of an environmental factor that might be missed in a design document.
When selecting stainless steel to use for making any custom wire or sheet metal form, it’s important to consider as many environmental factors as possible. This helps to ensure that the stainless steel basket, tray, or part will resist corrosion for as long as possible, rather than rusting right away.

Why Is It Called Stainless Steel?
The term stainless steel is a reference to the alloy’s tendency to resist rust under normal conditions. Scientific American states that “the chemical elements in stainless steel react with oxygen from water and air to form a very thin, stable film … The presence of the stable film prevents additional corrosion by acting as a barrier that limits oxygen and water access to the underlying metal surface.
This layer of rust is so thin that the human eye typically cannot see it without aid, giving the surface appearance of the steel its characteristic “stainless” appearance. Now, let’s dive a little deeper!
