Which field of material should be improved? What should we do to address this issue? China’s metal raw materials are not ideal, and this fact imposes restrictions on the production and development of engines for aircraft and motor vehicles. Which material fields need improvement, and what can be done to do them well? Answer: 1. China’s classification system for metal materials still uses the old standards from over a decade or even several decades ago, which is now quite different from those in Europe and the United States. When we use stainless steel SS, foreign countries use 304 and 316L ； When we first started to distinguish them, we didn’t know anything about ASTM A-638 GR 660 SS either. In terms of materials, since we are unable to develop them on our own, we need to introduce standards in a timely manner, assimilate them, and then produce them ourselves. First, let’s understand the differences between materials, as well as the differences between us and others. 2. Research, development, and widespread application of metal smelting technologies. 3. Teaching and research on new technologies and materials in universities. 4. Machining technology and digital lathe machining technology. 5. **Promotion of new materials and processing technologies, and restrictions on old technologies. 6. Both you and I must work hard to make the country strong, prosperous, and educated*, through our work.

We currently have world-leading equipment, but the products we produce are not as good as those from top foreign steel mills. The manufacturing of many high-precision devices still relies on material standards from the 1960s. The reason is that it’s been done this way in the past, and no one wants to take responsibility. And we often use a bit of cleverness, thinking that in some areas things can be streamlined. In the end, every aspect was simplified a bit, which resulted in poor quality. Sometimes, focusing only on immediate benefits without considering the long term results in restrictions on the development of new products. Furthermore, foreign steel mills each have their own strengths, while our steel mills tend to rush into whatever offers the highest profits. When developing new products, people often like to make decisions on a hunch, without conducting thorough investigations or research. Later, due to the pressure of the project, although the task was completed, the results of the development were not entirely perfect.

Reply 1# wo_call_you There is a wide range of metal materials. Here I only take the steel sector as an example. Most of my opinions will likely apply to other metal material sectors as well, or even to non-metallic materials. All of these problems stem from our planned economy system. China’s steel standards originated in the 1950s and were based on the Russian model; they became mandatory due to the characteristics of the planned economy. China is still behind developed countries in terms of the diversity and quality of its steel products. In particular, the current product portfolio is severely unbalanced: there is an oversupply of low-end steel products for general use, while high-value, high-tech products remain in short supply. To address these issues, China must first base its steel products on market demands. To save time and financial resources, it is better to learn from the best practices available. China should make use of existing voluntary consensus standards, such as adopting ASTM standards either directly or with some modifications, obtain technology transfer from globally established manufacturers, diversify and balance its production lines, improve product quality, and reduce costs.

Will these companies truly want to see us succeed, or will they keep the best for themselves? Do they really hope for our development? Will they still keep the best technology for themselves?

I’m not familiar with this; I’ve learned about it. Below is the English translation of what appears within, for everyone’s reference. China’s metal materials are not yet perfect, which hinders the production and development of engines used in airplanes and automobiles. Which area of materials needs improvement? What should we do to address this issue? Which aspects of metal materials need improvement? What should we do to address these issues? There are many different types of metal materials; here I will use the steel industry as an example. Most of my opinions are likely applicable to other metal material industries as well, or even to non-metallic materials. This is because all of these problems stem from our planned economy system. My perspective may also apply to most other fields of metal materials, including non-metallic materials. Because all these problems stem from our planned economy system. China’s steel standards originated in the 1950s and were based on the Russian model. They became mandatory due to the planned economy. China is still behind developed countries in terms of the diversity and quality of its steel products. In particular, the current product range is highly unbalanced: there is an overabundance of low-end steel products for general use, while high-value, high-tech products remain in short supply. This is the result of a central planned economy. China still lags behind developed countries in terms of steel diversity and product quality. In particular, there is a severe imbalance in current production: there is an oversupply of low-end steel products, while high-quality steel and high-tech products remain in short supply. To address these issues, first and foremost, China should tailor its steel products to meet market demands. To save time and financial resources, it is better to learn from the best practices. China should make use of existing voluntary consensus standards, such as adopting ASTM standards directly or with some modifications, obtain technology transfer from globally established manufacturers, diversify and balance its production lines, improve product quality, and reduce costs. Save production time and costs, and learn the best techniques. China should adopt established unified standards; it should use ASTM standards directly or make some modifications to them, and seek technology transfer from established manufacturers around the world as well as diversified operations in order to balance production lines, improve product quality, and reduce production costs.

Actually, this involves quite a lot of factors – whether it’s trivial matters or systemic issues. There are many people from within the country who excel in the field of metal materials; so the issue isn’t the lack of talent. But after investing so much money and effort over the course of a year, it seems that the gap between these companies and those foreign companies has only grown larger. Here’s a small suggestion: companies can provide those scraps to schools for use in research free of charge. Some materials have to be purchased in large quantities, and even if schools have the funds, it can be difficult to acquire them. By providing these materials, either free of charge or at a reduced cost, to research institutions, companies can take action promptly once results are achieved through that research. This way, a lot of trouble can be avoided

Most foreign steel products are indeed superior to ours. I think our equipment is still a bit outdated, and more importantly, the quality of our workforce is inadequate; there is also a lack of investment in technical capabilities. There is a shortage of personnel involved in developing new products and new manufacturing processes. In fact, there are various reasons for this, and comprehensive improvement requires efforts from all aspects. The competition mechanism in the domestic steel market is imperfect ； 1. There is a gap in smelting equipment and technology ； 2. There are differences in the level of product standards ； 3. There are differences in the level of enterprise management. 4. There are differences in the professional capabilities and dedication of employees. 5. There are deficiencies in the standardization of the market economy

Agree with floor 5. We need to establish a new cycle: market demand, incentives from economic benefits, technological innovation, the promotion and improvement of standardization, and the widespread adoption of new products. An important point is that we need to recognize that there are gaps on our side, and standards exist abroad. Only by meeting foreign standards can we reach the international average level. Hehe, the revolution is not yet complete; comrades must keep striving. For economic benefits, for a difference of just one millimeter, we never give up or abandon.
