The rapid development of China's steel production, from scratch, from imitation to their own research and development, in just 50 years, China's steel production has become the world's highest. Most of the foreign standard steel grade and in scientific research and manufacture of die steel, basically all production and research work in our country. Through reorganization of the steel grade and standard revised several times, has initially formed relatively complete steel series, with Chinese characteristics in the die steel production technology, double vacuum melting, electroslag remelting, ingot high temperature homogenization treatment, with great multidirectional forging or rolling garment or large hydraulic press breakdown and precision forging, forging and vacuum annealing, and to further improve the purity of steel, refined organization and improve to the performance of steel, etc.
