Stamping NAK80 die steel industry standardization
Since the reform and opening up more than 30 years ago, the mold manufacturing industry has gained rapid development. As the foundation of the mold manufacturing industry, what is the development status of the mold steel industry? Can it meet and adapt to the rapid development of mold industry? Experts believe that die steel production technology has made rapid development, experienced from scratch, from imitation to self-development process, only a few decades.
According to statistics of 15 special steel mills in China, the output of alloy tool steel has reached 400,000 T in recent years. Among them, the output of alloy die steel is more than 320,000 T, and the output of domestic die steel has ranked the top in the world. Most of the foreign standard steel number and die steel number in the research and production trial, domestic production and development work has been carried out. Stamping NAK80 steel through several kinds of consolidation and standard revision, with Chinese characteristics has been developed steel series, the steel production technology, variety quality, scientific research and development and application, etc., have made a lot of new achievements, not only can basically meet the need of domestic mold manufacturing, and some exports, make domestic NAK80 die steel has a foothold in the world.
Now the world's major industrial countries have formed a relatively complete stamping NAK80 die steel industry manufacturing and processing standards, and the development of national or association die steel industry standards, industry standards is stamping die steel product quality has been rapidly and effectively improved.
Mold is an indispensable special basic equipment in the manufacturing industry, mold steel is an important raw material for mold manufacturing, widely used in cold stamping, hot forging, die casting mold manufacturing, so the development of mold steel industry is crucial to the impact of the mold industry. Due to the late development of die steel industry in China, there is a gap between die steel industry and developed countries. There is a big gap with developed countries in many aspects, there is still a lot of work to be done in the future, that is, the NAK80 mold steel manufacturing industry standards, there is still a long way to go.
