Importance of Hardness in Tool Materials

Hardness is a crucial property in tool materials as it directly relates to their durability and effectiveness in performing cutting or shaping tasks. The harder a material is, the better it can resist deformation, scratching, or indentation, making it more suitable for use as a tool.

Explanation: Hardness is a measure of a material's resistance to deformation, and it is often associated with how well a material can withstand scratching or indentation. In the context of tool materials, hardness is an important property as it determines the tool's ability to cut or shape other materials. The higher the hardness, the more durable and effective the tool.

Based on their relative hardness, the tool materials can be ranked as follows:

d. steel: Steel has a moderate hardness and is commonly used for a wide range of tools.

b. steel carbide: Steel carbide, also known as cemented carbide or tungsten carbide, is much harder than steel and is often used for cutting tools, drill bits, and inserts.

c. low carbon: Low carbon steel has lower hardness compared to steel and steel carbide but is still harder than some other materials.

a. high speed: High-speed steel (HSS) is a type of tool steel that is heat-treated to enhance its hardness. It is commonly used for cutting tools and drill bits.
