ANS:B - high carbon steel

High carbon steel is a type of steel that contains a higher amount of carbon compared to other types of steel. Typically, high carbon steel contains between 0.6% to 1.5% carbon by weight. The increased carbon content gives high carbon steel several distinctive properties:

1. Strength: High carbon steel is known for its high strength and hardness. The presence of carbon increases the steel's ability to form strong, durable bonds with other elements, resulting in a material that is well-suited for applications requiring high tensile strength and wear resistance.
2. Hardness: High carbon steel can be heat treated to achieve a very high level of hardness. Through processes such as quenching and tempering, the steel can be hardened to withstand heavy loads and abrasive forces without deforming or wearing down easily.
3. Edge Retention: Due to its hardness, high carbon steel is commonly used in applications requiring excellent edge retention, such as in cutting tools and blades. The steel can be sharpened to a fine edge and maintains its sharpness for a longer period, making it suitable for tasks that require precision and cutting efficiency.
4. Wear Resistance: High carbon steel exhibits excellent wear resistance, making it ideal for applications involving abrasive materials or repeated impact. It can withstand friction and wear without losing its structural integrity, making it suitable for components subjected to heavy wear and tear.
5. Brittleness: While high carbon steel offers superior strength and hardness, it is also more brittle compared to low carbon steels. This brittleness can make the steel more prone to cracking or breaking under sudden impact or stress if not properly heat treated or handled.
6. Machinability: High carbon steel can be more challenging to machine compared to low carbon steels due to its hardness. Specialized machining techniques and tools may be required to work with high carbon steel effectively.
