Iron and steel Introduction to their science Explain that Stuff

Jul 30, 2017 The reason we so rarely see pure iron is that it combines readily with oxygen. Indeed, iron's major drawback as a construction material is that it reacts with moist air (in a process called corrosion) to form the flaky, reddishbrown oxide we call rust. Iron reacts in lots of other ways too—with elements ranging
