Strength of metals is normally measured by the tensile strength as the main measure although this is not the only property as hardness is another big factor. Basically, iron is soft and steel is hard. Plain iron is stretchy and does not corrode quickly, whereas steel is much stiffer and corrodes more quickly. The tensile strength of cold worked iron is about half that of an average steel, likewise the hardness is about half that of steel too. Pure iron, which is rarely used, is even weaker and softer again and a bit more like softer materials like copper and aluminium. Where confusion comes in is that there is another iron - Cast Iron - which is totally different to both iron and steel. Cast iron is very hard and tough but incredibly brittle so its properties are very different.
Every material is made up of atoms which are very small parts. Some atoms hold together quite well, which is what makes some solid materials hard. Something made of pure iron is softer than steel because the atoms can slip over one another. If other atoms like carbon are added, they are different from iron atoms and stop the iron atoms from sliding apart so easily. This makes the metal stronger and harder.
In general, metal alloys are stronger than "pure" metals because
the introduction of different elements into the crystal lattice helps to
prevent "slip" along imperfections in the lattice.
In the case of iron, the presence of small amounts of manganese,
copper, niobium, titanium, and/or vanadium alters the microstructure
and helps to keep the grain-size small, which increases the yield strength.
As noted by other respondents, these additives also impede the
process of rust.
By strength, if you mean durability, then I say steel is stronger than Iron. Iron corrodes pretty easily.
Iron gets corroded easily compared to iron. Thus in course of time they lose their strength. Steel an alloy of iron has the tendency to avoid corrosion in them.
yes,
because MAN OF STEEL is stronger than IRON MAN 3!! lol jk :D
To answer your question, steel can be made stronger than iron, but in the process loses its ductility.
Steel is Stronger, different properties :)
Its based on the carbon content which it have.... Basically steel has lesser carbon than iron so it doesn't get oxidized .....though the rust never occurs......
Steel is stronger NEXT QUESTION
grrrrrrr..i thought iron is stronger..silly mehh
and i get to know lots of skyscrapers are made of steel in it rather iron..grr -_- ughh
Is it..? Is it the steel that made skyscrapers strong compared to iron..? -_-
