Steel is iron plus carbon. Iron on its own is wrought iron (gates, hinges, that type of thing). Far too brittle to make usable armour. Steel is the material used to make swords, chain mail, etc.
not correct. Wrought iron falls into the same proportions of iron and carbon as low-carbon steel. the differences include grain, crystal shape, and slag inclusions. And cast iron usually exceeds steel in carbon content.
Iron plate (made by hammering out wrought iron ingots into sheets) makes dandy armor... but not as good as steel.
