    The difference?

    Iron is elemental.  Iron has a higher melting point than steel with it's added carbon. 

    Iron is ... ? Simple; it has  very predicable properties.  Alone it is somewhat resistant to rust, but the rust produced by pure iron is not held tightly on it's surface.  Wrought iron with it's silica impurities is very resistant to rust. Wrought iron is easily worked at higher temperatures than pure iron, it's working temperature higher makes it soft and soft longer so it can be worked longer before reheating to continue manipulating it.

    Iron with added elements mostly carbon because it is very cheap is more prone to rust, is tougher, can be hardened by heating and rapid cooling, has properties by 'tempering' to make it less brittle and resistant to shock. It is also less malleable at working heat, it takes a greater effort to manipulate it than pure iron.

     

    Iron with a high amount of Chromium and Manganese added is rust resistant and referred to as 'stainless steel'.   Add Nickel to iron and you can produce a steel that will not easily burn. Stainless steels take greater amounts of energy to form at working heat, and also have greater amounts of thermal shrink as they cool.

     

    Different alloys of steel  can produce a wide varieties of steel with wide varieties of properties.  Some alloys with cobalt are resistant to wear at high temperatures. Adding Tungsten makes a very hard steel.

    Iron is an element that is dug from the ground as Iron ore , a stone. The Iron ore has to be heated in a furnace until the iron melts and is extracted from the stone. The properties of Iron include being brittle and can not be drawn out in to a wire. By adding carbon to liquid Iron along with some other trace elements we can change the properties of the metal and it becomes steel. The exact amount of carbon added will give different types of steel , mild steel , high tensile steel etc. Steel can be worked more easily than Iron as steel is not brittle and can be hammered in to different shapes as a blacksmith can make horse shoes etc.

    So Steel is made from Iron , Carbon and mixture of other metals to give special characteristic properties.

    Steel has carbon in it.

    Iron is an element.

    Steel is an alloy (mixture) of iron and other elements.

    The carbon content.

    Pure Iron has no carbon in it. This makes iron a rather brittle metal. However, it tends to be very resistant to oxidation (rust).

    However, when iron is alloyed to carbon, you form steel. It will rust more easily.

    The percentage mass of carbon ranges from 0.1% to 1.5%.. This makes different steels. from 'Razor Strip' ,which can be honed to a very sharp edge., the strip steel for making white goods and car bodies, to forged steel for making tools.

    Steel can be further alloyed with chromium, nickel, tungsten etc., to make stainless steel, hard wearing steels such as railway line junctions/points/crossovers.

    Stainless steel (Iron, carbon chromium and manganese) has the characteristic of NOT rusting, but you cannot hone it to a razor edge.

    Hard wearing steel Iron, carbon, tungsten .

    Iron, Fe, is straight out of the ground as iron ore. It has no other elements mixed in. Steel is the iron, but it has other elements mixed into it to make it harder and often rust proof.

     Iron is a metal element that occurs naturally on Earth. Steel is a man-made alloy that's made by mixing iron and carbon together.
