Corrosions steel - Import export

A clean stainless steel surface will generate its own passive oxide layer when exposed to oxygen. It is this oxide layer that gives stainless steels their corrosion resistant qualities, it is possible however to accelerate the formation of this layer by chemical passivation.

Stainless steel derives its corrosion resistant properties from a thin oxide film on the surface, often referred to as a passive layer. Surface contamination can prevent the formation of the passive layer and cause stainless steel to corrode. Heat tint or weld burn discolouration are such surface contaminants and require removal.
