China's stainless steel fasteners are actively developing

Inside experts said that behind the construction of the behemoth, there are indispensable functions of small stainless steel fasteners. Although they are only small participants, they have a crucial impact. Because of the importance of its connection, consumers have gained more favor for the brand in purchasing.

"Stainless steel fasteners are also called standard parts in the market. They are a general term for a type of mechanical parts used when two or more parts (or components) are fastened and connected into a whole. It is widely used in All kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, molds, instruments, meters and supplies. "Luo Baihui, Secretary General of the International Model Association, said that with the development of China's manufacturing industry, stainless steel fastening As one of the products with large import and export volume in China, achieving international integration has important practical significance for promoting the development of Chinese stainless steel fastener companies to the world and promoting the full participation of stainless steel fastener companies in international cooperation and competition. Strategic significance. Due to the specifications, dimensions, tolerances, weight, performance, surface conditions, marking methods, and specific requirements of items such as acceptance inspection, marking and packaging, each specific stainless steel fastener product is specified in several national (industry) standards Among them, there are English, German and American systems, for example.

The machinery industry is one of the main users of stainless steel fasteners. Due to China's late recognition of the important position in the machinery industry and a long-term lack of investment, the entire industry has a poor foundation, a weak foundation, and weak strength. In particular, with the improvement of the level of Chinese mainframes, the bottleneck phenomenon of mechanical basic parts lagging behind the mainframe has become increasingly apparent. In recent years, although the state has provided some support in technology introduction, technological transformation, scientific research and development, etc., compared with the current market demand and foreign levels, there is still a small gap, which is specifically manifested in: fewer product varieties and low levels , Unstable quality, high early failure rate, and poor reliability.

Stainless steel fasteners are the main basic products of the machinery industry. The development of the machinery industry also puts forward higher requirements for stainless steel fasteners. Luo Baihui believes that the current domestic standard stainless steel fasteners have always been in oversupply, while high-grade stainless steel fasteners (high temperature, special-shaped, titanium-plastic composite, special performance and other stainless steel fasteners) are in short supply and rely on imports. The State Machinery Bureau listed "ordinary standard fasteners" as restricted development products, and "high-strength special-shaped fasteners" as current encouraged development products. With the improvement of national industrialization level and technological progress, the use of high-strength stainless steel fasteners has gradually increased.

It is understood that during the 12th Five-Year Plan period, the number of construction machinery products such as loaders, excavators and road rollers will reach 6 million units and the annual sales will be around 50,000 units. According to this estimate, the annual demand for high-strength stainless steel fasteners will be approximately 10,000-30,000 tons. The basic parts represented by stainless steel fasteners are not only the basic industries of China's equipment manufacturing industry, but also an important foundation for various fields of national economic construction. During the 12th Five-Year Plan period, while maintaining some cost advantages, the industry must rely on new advantages such as technological progress, quality improvement, and product cost performance to achieve sustainable development. It is estimated that by the end of 2015, the total output of the whole industry will reach 7.5 million to 8 million tons; under the overall situation of expanding exports, export products will show a volatile growth trend, and the average annual export growth rate is expected to be 8% to 10% during the 12th Five-Year Plan By 2015, the total export value of the whole industry will reach 30 billion yuan.

Industry experts said that domestic large and small stainless steel fastener companies should look to the future. "High-speed rail", "aerospace", "highway", "airport" and other national key construction projects are providing opportunities for tight enterprises to move toward high-end. Add 3400 aircraft, National Development and Reform Commission invested 800 billion yuan to build rail transit in 6 cities, according to 36 plans to build urban rail transit project city planning, by 2020, the new business mileage of urban rail transit will reach 6560 kilometers, stainless steel rail The demand for fasteners reached 5.5-7 billion yuan. These large-scale projects will greatly increase the demand for high-end stainless steel fasteners such as high-strength stainless steel fasteners and titanium alloys. It is not impossible to remove the "low-end" label.
