What Is Corrosion?
What is Corrosion?
When iron reacts with oxygen, it forms a reddish-brown oxide which we call corrosion or rust. This can be seen in its natural state, iron ore.
When steels corrode, they deteriorate and eventually decay over time. Immersion in water, saltwater and salt air will accelerate the natural corrosion process.
Iron reacts readily with air and water, so that is why chromium is added where a steel application needs a material that doesn’t rust easily, such as some grades of alloy and stainless steels.
