their both metals
aren't they the same thing
The main difference between cast iron and mild steel is the carbon content. Mild steel has a lower carbon content than cast iron. This makes cast iron brittle, while mild steel is much harder.
Yes. Steel is primarily iron with up to 2.1% carbon added, forming the iron alloy known as steel.
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.
No. Iron is a pure metallic element. Steel an alloy of iron iron with something else added, usually carbon, to give it more strength.
Cast iron is more brittle then mild steel
Steel is an alloy if iron, consisting mainly of iron. Steel is both stronger and lighter than iron so is more efficient to use in buildings and other structures.
It reduces the cost of transporting Iron to a Steel manufacturing plant.
The amount of carbon in iron is greater than 2 percent. Iron, steel is more difficult. Steel is more resistant to damage from iron.
Steel is an alloy of carbon and iron. If the percentage of carbon is more than 2% then it is called cast iron.
It depends on what you want to use it for. On the Moh's scale, steel is somewhere between 4 and 4.5, whereas iron is between 6 and 7. In swords, both iron and steel kinds have appeared, but steel is slightly better than iron due to its strength-to-weight ratio and its flexibility. Keep in mind, steel--unlike iron--is made of different metals to improve its strength. For piping, steel would be better (but not the first choice among other materials to use). Steel is also more resistant to rust, than iron, and the weldability of steel is better than iron.
Steel is made of iron to which is added between 0,02 % and 1.67 % of carbon.If you go over 2% of carbon, you'll get cast iron instead of steel.
