What is Steel???

Steel is also known as cast iron. It is a type of steel that is easily mould and ductile. Steel also main structural material and used as connection, link and base plate.


Type of Steel

  • Mild Steel
  • High Tensile Steel
  • Cast Iron
  • Pig Iron
  • Wrought Iron


Mild Steel

  • Material normally used in steel work construction.
  • Properties of mild steel:
  • Tensile stress strength
  • Flexibility
  • Elongation
  • Corrosion Resistance
  • Fire Resistant
  • Pengcuacaan


High Tensile Steel

  • Has high yield tensile strength.
  • Usually used:
  • In pre-stressed concrete work.
  • Cable for suspension bridge and high tensile bolts.


Cast Iron

Suitable to be used to build structures that have a low tensile stress and dynamic loads Used in:

  • Pipe
  • Cylinder head
  • Wheels
  • Stamping tool eye


Pig Iron

  • It should not be used for engineering purposes because it is key ingredients for making cast iron, wrought iron and steel.
  • Steel splinters and fragments of iron needed for:
  • Basic materials for making wrought iron, cast iron and steel.
  • Perusion to be indigo blue, and blue prints.
  • Electromegnet iron cores for the telephone and motor systems.


Wrought Iron

Welded wrought iron because of the simple pleasures of a career high: It is used as an ornamental iron work, making pies, sheet metal and stainless wagons because of its corrosion resistance.


Advantage of Steel

  • Available in various shapes.
  • Has high tensile strength and experiences long duration of plastic properties.


Disadvantages of Steel

  • Easily corrode when exposed to atmosphere.
  • Weak at high temperature.
