properties of steels

• steels


  are alloys of iron that contain specific amounts of carbon and other metals
• what can carbon steels be mixed with?

  iron can be mixed with varying amounts of carbon
• what happens if you add more carbon?

  higher the carbon, the harder and the more brittle the steel
• high carbon steel


  strong but brittle

  carbon - 0.45%-1.5%
• low carbon steel

  soft and malleable

  carbon - 0.25%
• alloy steels


  iron is mixed with other metals to give particular properties
• stainless steel


  alloy of chromium and/or nickel

  hard, resistant to corrosion
