As the first blueprint to describe a manufacturing powerhouse from the national strategic level, "Made in China 2025" clarifies the strategic tasks and priorities, the new generation of information technology industry, high-end CNC machine tools and robots, aerospace equipment, marine engineering equipment and high-tech ships, advanced orbit Ten key areas such as transportation equipment, energy-saving and new energy vehicles, electric power equipment, agricultural machinery equipment, new materials, biomedicine and high-performance medical equipment have become the focus of reform.
As the material basis and leading material of social development, especially alloy steel in iron and steel materials has attracted much attention, and stainless steel is an important part of it. With its superior stainless properties, corrosion resistance, strong toughness, high temperature resistance, low temperature resistance, wear resistance, abrasion resistance and good manufacturing processability, stainless steel plays an important role in the national economy, national defense construction, especially in the manufacturing industry. Development plays an important role in promoting.
Stainless steel is a traditional material because it has a history of more than 100 years of research and development and application; it is also a new type of material because new varieties are constantly being developed, such as different types of super stainless steel series, resource-saving stainless steel, high toughness and high strength (2000MPa level) Stainless steel, nano stainless steel, etc.
Stainless steel is a structural material as well as a functional material. It is an integrated material of structure and function, such as non-magnetic stainless steel, soft magnetic stainless steel, damping stainless steel, shape memory stainless steel, stainless steel with different expansion coefficients, etc. In short, functional stainless steel is the steel with the most development prospects and development potential among functional alloy steels.
The development status and trends of stainless steel are: (1) The quality and performance of stainless steel are advanced. It is mainly manifested in ultra-high cleanliness, ultra-high uniformity smelting and casting technology, whole-process ultra-fine structure control technology, steel appearance and shape quality control technology, etc. (2) Diversification and multi-function of stainless steel varieties and specifications. (3) Compounding of stainless steel homogeneous materials. (4) Functionalization of stainless steel structural materials. (5) Computerization of stainless steel design. (6) The flexibility, ecology and intelligence of stainless steel production technology. (7) In-depth application research of stainless steel. Work with users to improve the quality and performance of old steel grades, develop new uses, and develop new steel grades. (8) Pay attention to the research on the basic theory of stainless steel, especially the mechanism of local corrosion resistance, abrasion mechanism, strengthening and toughening mechanism of ultra-high-strength stainless steel, and related mechanisms of functional stainless steel.
The innovation-driven development of stainless steel varieties, quality, and brands will make due contributions to the realization of the goal of "Made in China 2025" and lay the foundation for China's stainless steel production and consumption to become a stainless steel powerhouse.
Materials are the material basis and forerunner of social development, the support for the development of the national economy, national defense and military industry, and an indispensable and important supporting technology for China's manufacturing from a manufacturing power to a manufacturing power. Therefore, it is imperative to vigorously research, develop and promote the core technologies of intelligent manufacturing, and transform China's manufacturing from output-efficient to quality-effective, among which the use of advanced steel materials including stainless steel is imperative.
