Experts say that behind the construction of giants, there are small stainless steel fasteners that are indispensable. Although they are only small players, they have a crucial impact. Because of the importance of connection, consumers have an extra favor for brands in purchasing.
"Stainless steel fasteners are also known as standard parts in the market. They are a general term for a class of mechanical parts used when two or more parts (or components) are fastened together to form a whole. It is widely used in All kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, molds, instruments, meters and supplies, etc. "said Luo Baihui, secretary general of the International Mould Association. At present, with the development of China's manufacturing industry, stainless steel fastening As one of the products with a large import and export volume in China, it is in line with international standards. It is of great practical significance to promote Chinese stainless steel fastener companies to the world and promote the full participation of stainless steel fastener companies in international cooperation and competition. Strategic significance. Due to the specific requirements of each specific stainless steel fastener product specifications, dimensions, tolerances, weights, properties, surface conditions, marking methods, and acceptance inspection, marking and packaging items, it is specified in several countries (industry) standards Chinese, for example, British, German and American.
The mechanical 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 its long-term lack of investment, the entire industry has a poor foundation, a weak foundation and weak strength. Especially with the improvement of China's main engine level, the bottleneck phenomenon that mechanical basic parts lag behind the main engine becomes increasingly apparent. In recent years, although the state has given certain support in terms of technology introduction, technological transformation, scientific research and development, etc., compared with the current market demand and foreign standards, there is still a big gap, as shown in the following: less product varieties and lower levels , Unstable quality, high early failure rate, and poor reliability.
Stainless steel fasteners are the main basic products in the machinery industry. The development of the machinery industry has also put forward higher requirements for stainless steel fastener products. Luo Baihui believes that the current domestic standard stainless steel fasteners have always been oversupplied, while high-end 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 Bureau of Machinery lists “common standard fasteners” as restricted development products, and “high-strength shaped fasteners” as currently encouraged development products. With the improvement of the country's 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 rollers will reach 6 million units, with an annual sales volume of about 50,000 units. based on this estimate, the annual demand for high-strength stainless steel fasteners is about 2 10,000 to 30,000 tons. The basic parts represented by stainless steel fasteners are not only the basic industry of China's equipment manufacturing industry, but also an important foundation for all areas of national economic construction. During the Twelfth Five-Year Plan period, while maintaining some cost advantages, the industry must rely on new advantages such as technological progress, quality improvement, and cost-effectiveness to achieve sustainable development. The total output of the industry is expected to reach 7.5 million to 8 million tons by the end of 2015; under the overall situation of expanding exports, export products will show a volatile growth trend. The annual average export growth rate during the 12th Five-Year Plan period is expected to be 8% to 10% By 2015, the total export value of the entire industry will reach 30 billion yuan.
Industry experts said that domestic large and small stainless steel fastener companies should look to the future. National high-speed rail, aerospace, highway, and airport projects such as national key construction projects are providing opportunities for tight companies to move to the high end. Add 3,400 aircraft, NDRC invested 800 billion yuan to build 6 cities' rail transit. According to the plan of 36 cities that plan to build urban rail transit projects, by 2020, the new operating mileage of urban rail transit will reach 6,560 kilometers, and the rail stainless steel The demand for fasteners reached 5.5-70 billion yuan. These large 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.
