Steel

  1. 1. Steel <br />
  2. 2. Steel-production <br />Alloy, consisting of mainly iron containing a carbon content of 0.2% to 2.1% (weight). Tungsten, chromium and manganese are also used. <br />
  3. 3. Steel-Tensile Strength<br />Comparatively high, highly resistant to fracture or breakage <br />
  4. 4. Steel-Ductility<br />High vast range of shapes and structures <br />
  5. 5. Steel-Malleability<br />High (compressed into sheets) <br />
  6. 6. Steel-Durability<br />Hardness is high, long lasting, great resistant <br />
  7. 7. Steel-Conductivity<br />Good Conductor of heat and electricity <br />
  8. 8. Steel-Luster<br />Attractive out appearance <br />
  9. 9. Steel-Rust Resistance<br />With additional elements (nickel, molybdenum, and chromium) <br />
  10. 10. Steel-Facts<br />Most recycled material in U.S. (69% is recycled)<br />-83,000 tons of steel were used to make the Golden Gate Bridge<br />-600 steel or tin cans are recycled every second.<br />-It takes more than the wood of 40 trees to make a wood framed home - a steel framed home uses 8 recycled cars <br />
  11. 11. Steel-Uses<br />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 <br />
  12. 12. Steel-Lifecycle <br />
