Special steel industry: "thickness" looks forward to "thin hair"

Special steel industry structure limited capacity needs to be expanded

China is a big steel producer. In recent years, crude steel production accounted for more than 40% of the world's total, while special steel development has lagged behind. The output of special steel in the world's strong countries accounts for more than 15% of the total crude steel, while China is only slightly higher than 6%. The alloy steel with higher technical content in special steel products accounts for only 4.9% of China's, far lower than the world. Advanced level. At present, China's special steel production is mainly based on structural steel and other low-end products, high-speed steel, alloy mold steel and other high-end steel products with high technical barriers and strong profitability are mainly dependent on imports. With the continuous improvement of the technology and equipment level of domestic excellent special steel enterprises, the market share of high-end products will increase and the performance will continue to improve.

Currently many domestic steel production equipment is only equivalent to the international level in the 1990s, low productivity, limited variety, in technological advancement and technological innovation obviously can not keep up with the international pace. With the development of special steel industry, equipment is facing upgrading and upgrading. In addition to energy conservation and environmental protection requirements, quality control is a long-term problem faced by China's special steel industry. In addition, the technical level is out of line, the lack of technical research and development capabilities and the weakening of technology imports, and the long conversion time of laboratory R&D products all affect the capacity expansion of Special Steel.

Wide range of applications in the field of special steel

Special steel can be divided into structural steel, bearing steel, tool steel, die steel, spring steel, cold heading steel, special alloy and so on according to the application. Structural steel is used in all kinds of industrial machinery transmission parts, fasteners, structural parts, etc. Bearing steel is used to produce mechanical balls, bearings and bearing sleeves. Tool steel is used to manufacture all kinds of cutting tools, cutting tools, measuring tools and molds. Special steel has strict requirements on quality and performance, and its products are widely used in special fields such as aerospace, nuclear energy and military products.

Automobiles and machinery are the main downstream industries of Special Steel, of which about 35% are automobiles and 24% are machinery. It is the two most demanding markets in the special steel industry. The automotive industry is currently the most important application area for special steel, with special steel accounting for more than 60%. The traditional manufacturing industry represented by the machinery industry is a major basic industry of the national economy, a major consumer of special steel, and an important factor in the development of special steel in the past. At present, the manufacturing level of many large-scale complete sets of equipment manufacturing in China has reached the world-class level, but the limitation of key supporting parts is very common. The autonomy of parts and components will promote the development of related materials, and the special steel industry will benefit.

New materials for the power industry to upgrade the engine

As one of the key areas of new materials, high-quality special steel enjoys the huge pulling effect brought by other emerging industries. In the future, the development trend of domestic special steel enterprises should be to strengthen research and development, improve the production capacity of high value-added products, and seek import substitution. During the “Twelfth Five-Year Plan” period, high-performance special steel, as one of the six new types of materials that received key support, has become a catalyst for the rapid development of the special steel sub-sector.

High-end equipment manufacturing is the core driving force in the future development of high-end steel. "Five" high-end equipment manufacturing industry rose to a total market size of national industrial strategic level, aircraft, high-speed rail, marine and energy is expected to more than 10 trillion, high-end steel market demand will be full speed. At the same time international demand for high-end manufacturing will also simultaneously enhance, our high-speed rail, power, wind power and other construction achievements attracted worldwide attention, also will open the door to the international market. China's future high-end manufacturing will go out the pace continues to accelerate, steel industry will benefit from it.
