With the rapid development of industrial technology, the manufacturing industry at home and abroad has widely adopted new technologies such as precision stamping, precision forging, and pressure casting, and molds have become their main forming tools. In many industries, mold costs have accounted for about 30% of the cost. Therefore, the improvement of industrial product quality, productivity, cost reduction, and product update speed depend to a large extent on the manufacturing accuracy and quality of the mold, manufacturing cycle, production cost, service life and other factors.

Die steel is an important technical and material basis for the mold industry. In the past few years, with the rapid development of the mold industry, the development of mold steel is also extremely rapid
