24/08/2008· Favourite answer. Yes ofcourse. The hardness of steel very much assosiated with carbon. Fo example, Cast Iron is most brittle nature and it break at a very low stress having carbon content more than 2 .

Wrought iron has an average tensile strength of about 25 tons per square inch, about half that of steel. But hardness is quite a different quality from tensile strength. Cast iron is extremely hard, but very weak in tension. Wrought iron is malleable, softer than some steel and harder than others.

13/03/2019· In general, cast iron is harder. As we define hardnss as a material's resistance to localised plastic deformation. The main difference between steel and cast iron is the carbon impurity atoms' concentration that you add in interstitial spaces of an iron crystal. In steel this concentration is less than in cast iron.

05/07/2015·Ł Answer Ernest Z. Jul 5, 2015 Carbon gives iron hardness by distorting its crystal lattice. Explanation: In a perfect crystal, the metallic bonds are so strong that a lot of force must be applied to make it deform permanently. Most crystals are not perfect, however, and iron is no exception. There are often vacancies in the atomic lattice. These vacancies alter the arrangement of other parts
Pure iron, for example, is very soft. Adding a small amount of tungsten to iron makes tool steel, which is harder than pure iron. Steels are examples of alloys. There are many types of steel.
