Here granular products made of calcium oxide, calcium carbide, calcium fluoride and others are applied.

What Is the Difference Between Iron and Steel? | Reference.com


What Is <b>the Difference Between Iron and Steel</b>? | Reference.com

The difference between iron and steel is that iron is an element, and steel is an alloy of iron, small amounts of carbon and another material, usually another element like chromium. Iron is alloyed with other elements to make it stronger and more useful and to keep it from rusting. There are thousands of different types of steel.
