Under the wise leadership of Chairman Hua and the Central Party Committee of the Communist Party of China, the people throughout the country deeply and thoroughly criticize the anti-Party clique of the Zhangjiang River and implement the strategic decision made by Chairman Hua in catching the Gangchung Governing and the rule of the country in an all-round way. The situation toward great rule, revolution and production is of great significance. In order to meet the needs of high-speed, high-efficiency, mechanization and automation of industrial production development, we trial-produced and produced tungsten carbide-based chromium-molybdenum steel steel cemented carbide. We know that the general alloy tool steel such as Cr12, CrWMn and other molds, its service life is shorter; and tungsten cobalt
