Corrosive substances that present potential problems should be studied in detail to determine the nature and seriousness of the problems they present. A large part of this evaluation should consist of air sampling conducted by an industrial hygienist or a person trained in air sampling techniques. The possibility of exposing employees to corrosives should be evaluated to determine the needs for controls and personal protective equipment.

Tin is widely employed in the manufacture of food containers and its electrochemical behaviour in the presence of organic acids has attracted considerable interest.

The variety of conditions in which corrosion appears and its various forms makes corrosion analysis a complex process. Because of the variety of corrosion forms and conditions, there is no universal corrosion test for all situations.

For the precious metal wires, the range of industrial applications is wide and varied.

Cast iron is known for quickly disintegrating if not kept in a wet environment after excavation from the sea. This iron can be corroded by graphitization which leaves behind a metal core but has an outer shell of graphite that contains iron corrosion products.
