STEEL

Steel is also know 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.

WHAT IS STEEL??

• Mild steel

• High tensile steel• Cast iron• Pig iron

• Wrought iron

TYPE OF STEEL

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

Mild steel

Mild steel bar Mild steel piping Mild steel channel

Example mild steel

•Has high yield tensile strength•Usually used :

- In pre-stressed concrete work

- Cable for suspension bridge and high tensile bolts

High Tensile Steel

High tensile steel bar High tensile steel rod

Example tensile steel that used in shanghai

Suitable to be used to build structures that have a low tensile stress and dynamic loadsUsed in:           - Pipe           - Cylinder head           - Wheels           - Stamping tool eye

Cast iron

Example of cast 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:

1.Basic materials for making wrought iron, cast iron and steel

2. Perusion to be indigo blue, and blue prints

3.Electromegnet iron cores for the telephone and motor systems

Pig iron

Example of pigers 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

Wrough iron

Example of wrough iron

Advantages and disadvantages of steel

ADVANTAGES DISADVANTAGES

• Available in various shapes.

• Has high tensile strength and experiences long duration of plastic properties.

• Easily corrode when exposed to atmosphere.

• Weak at high temperature
