Eutectoid/Pearlite steel:
- A 0.8% carbon steel or eutectoid steel is known as PEARLITE steel.
- This is much stronger than ferrite or cementite.
- It is a phase mixture of ferrite and cementite.
- It contains ferrite 87% and cementite 13%.
Hypo-eutectoid Steel:
- Plain carbon steels in which carbon percentage is less than 0.8% are called hypo-eutectoid steel.
Hyper-eutectoid Steel:
- Plain carbon steels in which carbon percentage is more than 0.8% are called hyper-eutectoid steel.
- High-Speed Steel is a high carbon tool steel, containing a large dose of tungsten. A typical HSS composition is: 18% tungsten, 4% Chromium, 1% Vanadium, 0.7% carbon and the rest, Iron.
- Cast irons have a chemical composition of 2.15–6.7% carbon.
