Alloy- iron and 0.05% - 0.25% carbon
What are the properties of mild carbon steel?
- Tough
- Ductile
- Malleable
- Good tensile strength
- Poor resistance to corrosion
What is the composition of medium carbon steel?
Alloy- iron and 0.25% - 0.45% carbon
What are the properties of medium carbon steel?
- Harder than mild carbon steel.
- More brittle than mild carbon steel.

What is the composition of cast iron?
Alloy- iron with 2.5% - 4.0% carbon and 1% - 3% silicon
What are the properties of cast iron?
- Hard skin
- Softer underneath
- Brittle
- Corrodes by rusting
What are the uses of cast iron?

What is the composition of pure iron?
100% iron (Pure)
What are the properties of pure iron?
- Soft
- Easily corroded
- Brittle
What are the uses of pure iron?
- It is too soft to be useful, so it is usually turned into steel
What are the uses of mild carbon steel?
- General engineering material (bridges, cars etc.)
