[0002] Die steel is a steel type used to manufacture dies such as cold stamping dies, hot forging dies, and die-casting dies. Dies are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances. The quality of the die directly affects the quality of the pressure processing technology, the precision, output, and production cost of the product. The quality and service life of the die are mainly affected by the die material and heat treatment in addition to reasonable structural design and processing accuracy.
