why steel is strong?

Answer 1

because carbon mixed with iron makes steel. Carbon is the thing that make iron strong . The result is steel.

Answer 2

Previous questions tell you an alloy that makes steel, but doesn't answer why steel is strong. Part of it lies in what alloying materials you use. The next important factor is what crystalline structure you may find(yep, metals have a crystalline structure, just like quartz, salt, etc). These include austenitic and martensitic structures for example.

When you realize what these things do to the overall effect and strength of steel, you can see that steel can actually be very brittle or very strong. When you think of "strong" think that the metal can absorb a lot of energy before it breaks. All materials have a "modulus of elasticity" and can be charted against their stress versus strain curve. the area below the curve is the energy that the material can absorb. Steel has a very large area below this curve and is therefore both strong and tough (as opposed to being strong and brittle, like tungsten carbide). This question lies in the realm of chemistry and metalurgy.

Answer 3

Steel is the combination of Fe(Ferrous) & C(Carbon). The percentage of carbon in steel is less so the steel is strong.

Answer 4

From a half-remembered chemistry lesson long ago, it is the carbon content in steel that gives it its strength.

Answer 5

Steel is allow of metals, and it has been researched much to make like that...

Answer 6

when Carbon , silicon , mangenese sulfur arrive into unit cell of iron they cause crystal atructure of iron being contracted or expand and this create a blockage for moving dislocation and cause strength.

Answer 7

due to its molecular arrangement

Answer 8

because of its composition
