The difference is percentage of carbon, the main alloy element. Those irons containing less than 2% carbon are known as steels while those containing more than 2% carbon are known as pig iron. Pig iron is obtained from iron ore by processing it with coke in a blast furnace. This pig iron is then further processed to reduce the carbon content in different furnaces to obtain steels. These steels can be then further processed to obtain alloy steels, stainless steels by adding elements such as silicon, manganese, chromium, nickel, etc.
What happens is that the carbon atoms fit into the latticework of the iron atoms, making it more rigid and stronger.
Iron is an element- a pure substance. It rusts (forms iron oxide) on exposure to water and air.
Steel of a mixture of two elements- iron and carbon.
Iron is the pure element, mild steel, or any steel is iron with a little bit of carbon added. The iron becomes mild steel, steel or any other type of steel depending on how much carbon is added to the iron.
Compounds of metals, steel and other materials that the alloy is known. It is pure iron.
Iron (Iron is the only pure metal that rusts, all other metals corrode)
Steel - Pure iron is a relatively soft maleable metal - the addition of small amounts of carbon and other elements during the steel making process add strength and hardness. High strength steels have more carbon than low strength steels, but more carbon also adds brittleness after a point. Silicon, Tungsten and Molybdenum are common alloying elements added to iron to make higher strength steels.
In essence nothing, a Cupola furnace is a type of blast furnace in that it is charged at the top and tapped at the bottom and air is blasted into the furnace via a wind belt and tuyres. A blast furnace in a steel works is a huge structure operated for long periods of time, it is charged with iron ore, coke and limestone and reduces the iron ore into pure iron. A Cupola furnace, as used in the foundry re melts pig iron, from the blast furnace, along with foundry scrap, steel scrap and scrap iron engine blocks and produced iron alloys of various specifications. A Cupola furnace is usually operated on a daily basis but some types can be continuously operated for several weeks

This is not pure iron but a special steel.
The main element from which steel is made is Iron (Fe) but steel is not pure - (not just iron) it is an alloy of iron and other elements, primarily carbon. Element MUST be pure substances and if steel were pure it would be Iron.
Pure iron is not a strong as steel and it is also prone to corrosion in the form of rust.
Steel is very resistant to corrosion. It is hard and strong. It is resistant to stretching, depending on the type of steel; low-alloy steel and nickel steel. Steel is maleable, but not 'soft' like pure iron, iron is much more useful when in the form of steel. Pure iron is weak, too soft to be used in construction or for any building purposes.
Steel, which has a higher tensile strenght than pure iron, would be toughest to break. Steel is an iron alloy.
Steel: It always contains some carbon and often other metals in addition to iron.
No. Iron is a pure metallic element. Steel an alloy of iron iron with something else added, usually carbon, to give it more strength.
Iron is a pure substance. It's an element (Fe) and a bar of Iron is no mixture. If it was pure iron, then by definition it would be pure. However iron is rarely pure, it is usually in alloy with something.
burns faster in pure oxygen as the percentage of oxygen is less in air
