Corrosion is a natural process, which converts refined metal to their more stable oxide. It is the gradual destruction of materials (usually metals) by chemical reaction with their environment.In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen.orrosion can also occur in materials other than metals, such as ceramics or polymers, although in this context, the term degradation is more common.
These can result from a number of causes including the method of application, the condition of the surface or any pre-treatment. Corrosion is an electro-chemical process which transforms steel influenced by oxygen and water, in iron hydroxyde (rust).Corrosion is most often caused when steel is exposed to atmospheric conditions, such as salt, moisture, and oxygen. A protective coating to the steel required to prevent corrosion.Corrosion of stainless steels can be categorised as one of:orrosion is most often caused when steel is exposed to atmospheric conditions, such as salt, moisture, and oxygen.
