With the rapid development of industrial technology, both at home and abroad, widely used in manufacturing precision stamping, precision forging, casting and other new technology. Forming mould has become the main tool. Many in the industry, the mould cost has accounted for about thirty percent of the cost. Industry, therefore, the improvement of product quality, productivity, cost reduction, product update speed, in large part depends on the precision and quality of mould manufacturing, manufacturing cycle, the cost of production, life and other factors.

Die steel mould industry is one of the most important technology and material basis. In recent years, with the rapid development of the mould industry, steel development is extremely fast.
