What defines Tool Steel?

• A. A type of metal used in structural applications
• B. Steel known for excellent strength and wear resistance
• C. A low-carbon steel used in machining
• D. A steel primarily used for decorative purposes

Answer: (B)

Tool steel is defined by its excellent strength, wear resistance, and ability to retain its hardness at elevated temperatures, which makes it ideal for manufacturing tools and dies. This type of steel is specifically formulated to withstand the demanding conditions commonly encountered in machining, cutting, and forming processes. Its unique properties enable it to maintain sharp cutting edges and resist deformation under stress, which are critical factors in tool performance. The other options do not accurately capture the essence of tool steel. For example, structural applications typically require steels with different properties suited for load-bearing rather than cutting. Low-carbon steels, on the other hand, lack the high hardness and wear resistance necessary for tool applications, making them unsuitable for the same purposes. Lastly, steel used for decorative purposes is designed with aesthetics in mind rather than the performance characteristics required in tooling environments. Therefore, the option highlighting tool steel's strength and wear resistance correctly reflects its defining characteristics.
