Steel is an alloy consisting mainly of iron with 0.2-2.1% carbon content, and is also alloyed with other elements like tungsten, chromium, and manganese. Steel has high tensile strength and ductility allowing it to be formed into a vast array of shapes, as well as high malleability enabling it to be compressed into sheets. Steel is also very durable and resistant to fracture due to its hardness, and can conduct both heat and electricity well when additional elements are included. Steel has many uses ranging from small items like knives to large structures like bridges and buildings.

2. Steel-production Alloy, consisting of mainly iron containing a carbon content of 0.2% to 2.1% (weight). Tungsten, chromium and manganese are also used.

3. Steel-Tensile Strength Comparatively high, highly resistant to fracture or breakage

4. Steel-Ductility High vast range of shapes and structures

5. Steel-Malleability High (compressed into sheets)

6. Steel-Durability Hardness is high, long lasting, great resistant

7. Steel-Conductivity Good Conductor of heat and electricity

8. Steel-Luster Attractive out appearance

9. Steel-Rust Resistance With additional elements (nickel, molybdenum, and chromium)

10. Steel-Facts Most recycled material in U.S. (69% is recycled) -83,000 tons of steel were used to make the Golden Gate Bridge -600 steel or tin cans are recycled every second. -It takes more than the wood of 40 trees to make a wood framed home - a steel framed home uses 8 recycled cars

11. Steel-Uses From a knife to a building, from a car to a razor, from a ship to a hair pin, from a train to a pot, from a bridge to a scalpel
