Die Steel is a type of tool steel used for making dies, molds, and cutting tools that shape or form metal and other materials. It is specially designed to withstand high pressure, wear, and repeated use during manufacturing processes. Die steel has excellent hardness, toughness, and wear resistance, which helps tools maintain their shape and performance even under heavy mechanical stress. Because of these properties, die steel is widely used in industries where precision and durability are very important.

Die steels are generally classified into different categories such as cold work die steel, hot work die steel, and plastic mold steel, depending on the temperature and type of work they perform. These steels usually contain alloying elements like carbon, chromium, molybdenum, vanadium, and tungsten, which improve strength, hardness, and resistance to heat or wear. Die steel is commonly used to manufacture forging dies, stamping dies, extrusion dies, casting molds, punches, and cutting tools. Due to its ability to handle extreme working conditions and maintain long service life, die steel plays a crucial role in automotive, construction, aerospace, and heavy manufacturing industries.
