  • Alloy steel – steel who characteristics are determined by the addition of other elements in addition to Carbon
  • Steel – an alloy of iron with small amounts of carbon; widely used in construction; mechanical properties can be varied over a wide range
  • Chromium steel, stainless, stainless steel – steel containing chromium that makes it resistant to corrosion
  • Chrome-nickel steel, Elinvar – Elinvar is a trademark for a kind of steel used for watch springs because its elasticity is constant over a wide range of temperatures.
  • Chrome-tungsten steel – a steel alloy made with chromium and tungsten
  • Austenitic manganese steel, manganese steel – a steel with a relatively large component (10-14%) of manganese; highly resistant to wear and shock.
  • Molybdenum steel – steel containing 10-15% molybdenum; properties are similar to tungsten steel
  • Nickel steel – an alloy steel containing nickel
  • Tool steel – alloy steel that is suitable for making tools; is hard and tough and can retain a cutting edge
  • Tungsten steel, wolfram steel – a very hard heat-resistant steel containing tungsten.
