Tool steel is a high-carbon, high-alloy steel specifically designed for manufacturing cutting, shaping, and forming tools. Known for its exceptional hardness, wear resistance, and heat resistance, it maintains sharp edges and durability under extreme conditions. Common types include cold-work, hot-work, and high-speed tool steels, such as 1.2344, 1.2510 and 1.2714. Cold-work tool steels excel in low-temperature operations, while hot-work variants withstand high temperatures. High-speed tool steels retain hardness even at elevated temperatures, making them ideal for drills and milling cutters. Tool steel undergoes precise heat treatment to enhance performance, ensuring toughness and longevity in demanding industrial applications like metalworking, machining, and die-casting.
