High-Speed Steel (HSS) is a type of tool steel known for its ability to withstand high temperatures without losing hardness. It is commonly used in cutting tools, such as drills and saw blades, due to its excellent wear resistance and toughness. HSS can maintain its cutting edge even when subjected to high-speed operations, making it ideal for machining metals. HSS is typically made from a combination of iron, carbon, and other alloying elements like tungsten and molybdenum. These additions enhance its properties, allowing it to perform effectively in various industrial applications. Its versatility makes it a popular choice in manufacturing and metalworking industries.
