The hydraulic system will have explosive growth in the future

Import substitution, stock explosion, maintenance market growth and infrastructure growth are the core drivers of industry growth.

The hydraulic components are the core components of the construction machinery. The scale of the industry is more than 30 billion yuan per year in the country, and the proportion of imported hydraulic components exceeds 70%. High-end products are almost entirely imported. The output value of hydraulic industry in various countries accounts for about 3% of the output value of the machinery industry, while China accounts for only about 0.18%. There is still room for development in the hydraulic industry in China.

Construction machinery has developed rapidly in recent years, and the stock has grown rapidly. The failure of hydraulic components has accounted for almost half of the failures in construction machinery. In the foreseeable future, the maintenance market scale of hydraulic components will explode. At the same time, the huge supporting market for mainframes of construction machinery, the current localization rate is not high, mainly depends on imports and foreign-funded enterprises in China, and the import substitution space is huge.

During the "12th Five-Year Plan" period, with the continuous development of the domestic mold manufacturing industry, it also put forward some new technical requirements for mold steel. It is understood that the diversification of mold manufacturing, large-scale, precision and pre-hardened development trend also requires that it increase efforts in the development of special steel, but also should vigorously develop high-quality domestic mold materials.

First of all, in the plastic mold steel, it is necessary to develop ultra-large specifications of the car bumper pre-hardened plastic mold steel; Second, in the hot work mold steel, to develop a new type of low-cost, high-life hot work die steel with independent intellectual property rights, development of super Pure, homogeneous tissue of hot work die steel; Thirdly, in cold work die steel, it is necessary to target the high-strength steel plate (tensile strength> 800MPa) cold stamping molding material and surface treatment technology. Continuous efforts to develop superior mold materials can promote the development of the domestic mold industry and lay a foundation for the domestic mold industry to take the road to a strong nation.
