Steel is an alloy of iron and small amounts of carbon, chrome and other metals. Steel is much, much harder than iron and is much more useful for making things out of.
Steel is used heavily in building construction, making land and sea vehicles of all kinds, and many household appliances. Some types of steel can still rust, but surgical and stainless steel are far less prone to rusting.
