One group is named hypoeutectoid steel (carbon content less than 0.8%) and the other is hypereutectoid steel (carbon content more than 0.8%). In hypoeutectoid steel, the equilibrium microstructure at room temperature consists of ferrite and pearlite; this ferrite is called proeutectoid ferrite

Hyper eutectoid steels have carbon contenta)equal to 0.83%b)more than ...
Hyper eutectoid steels are a type of steel that contain more than 0.83% carbon and up to 2% carbon. Let's understand why the correct answer is option 'B' in detail.
Definition of Hyper Eutectoid Steels
- Eutectoid steels are a type of steel that contain exactly 0.83% carbon, which is the eutectoid composition.
- Hyper eutectoid steels, on the other hand, have a carbon content greater than the eutectoid composition, meaning they contain more than 0.83% carbon.
Explanation of the Correct Answer
The correct answer is option 'B', which states that hyper eutectoid steels have carbon content more than 0.83% and up to 2%. This means that the carbon content in hyper eutectoid steels ranges from more than 0.83% to a maximum of 2%.
Importance of Carbon Content in Steels
- The carbon content in steels plays a crucial role in determining their mechanical properties and behavior.
- Low carbon steels (carbon content less than 0.25%) have good ductility and are easily weldable, but they have lower strength and hardness.
- Medium carbon steels (carbon content between 0.25% and 0.60%) have higher strength and hardness, but they are less ductile and less weldable.
- High carbon steels (carbon content greater than 0.60%) have the highest strength and hardness, but they are brittle and difficult to weld.
Properties of Hyper Eutectoid Steels
Hyper eutectoid steels, with a carbon content greater than 0.83% and up to 2%, have the following properties:
- High hardness: The increased carbon content allows for greater hardness in the steel, making it suitable for applications that require wear resistance, such as tools and blades.
- Reduced ductility: As the carbon content increases, the ductility of the steel decreases. Hyper eutectoid steels may exhibit lower ductility compared to lower carbon steels, which can make them more prone to cracking or breaking under certain conditions.
- Increased brittleness: Hyper eutectoid steels with carbon content closer to the upper limit of 2% can become increasingly brittle, reducing their toughness and impact resistance.
Applications of Hyper Eutectoid Steels
- Hyper eutectoid steels are commonly used in applications that require high hardness and wear resistance, such as cutting tools, springs, and high-strength wires.
- These steels are also suitable for applications where the material needs to retain its shape under high stress or in harsh environments.
In conclusion, hyper eutectoid steels have a carbon content greater than 0.83% and up to 2%, making them harder and less ductile compared to lower carbon steels. They find applications in industries where high hardness and wear resistance are required.
