Steels Used for High-Speed Machining:
- Steels used for making tools that are designed to machine materials with heavy cuts at high speeds are typically chosen for their ability to maintain hardness and cutting efficiency at elevated temperatures. These tools need to withstand the high stresses and temperatures generated during high-speed machining.
- Plain-Carbon Steel: Although plain-carbon steel is used in some cutting tools, it is not suitable for high-speed machining where heavy cuts are involved, as it tends to lose its hardness quickly at elevated temperatures.
- Low-Carbon Steel: Low-carbon steels are generally softer and more ductile, making them unsuitable for cutting tools that require high hardness and strength, especially in high-speed machining applications.
- High-Speed Tool Steel: This steel is specifically designed for high-speed machining. It retains its hardness even at high temperatures, which is crucial for tools subjected to heavy cuts and high-speed conditions. High-speed tool steel contains alloying elements such as tungsten, molybdenum, vanadium, and cobalt, enhancing its performance in these demanding applications.
- Medium-Carbon Steel: Medium-carbon steels offer better hardness and strength than low-carbon steels, but they still do not perform as well as high-speed tool steels under high-speed machining conditions.
Conclusion
Based on the required properties for high-speed machining with heavy cuts, the correct answer is:
3) High-Speed Tool Steel
This type of steel is specifically engineered to perform well under the demanding conditions of high-speed and heavy-cut machining, making it the best choice among the options provided.
