Behind the construction of the behemoth, there are small stainless steel fasteners indispensable. Although they are only small participants, they have a vital influence. Because of the importance of its connection, consumers have an added preference for brands in their purchases.
"Stainless steel fasteners are also called standard parts in the market. They are the 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 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 Model Association, said that with the development of my country’s manufacturing industry, stainless steel fastening As one of the products with a large import and export volume in China, it is of great practical significance to promote Chinese stainless steel fastener enterprises to the world and to promote the full participation of stainless steel fastener enterprises in international cooperation and competition. Strategic significance. Since the specifications, dimensions, tolerances, weight, performance, surface conditions, marking methods of each specific stainless steel fastener product, as well as the specific requirements for acceptance inspection, marking and packaging, are separately stipulated in several national (industry) standards There are, for example, the British system, the German system, and the American system.
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, weak foundation and weak strength. Especially with the improvement of the level of China's mainframe, the bottleneck phenomenon of mechanical basic parts lagging behind the mainframe has become increasingly apparent. In recent years, although the state has given certain support in terms of technology introduction, technological transformation, scientific research and development, etc., there is still a big gap compared with the current market demand and foreign levels. The specific manifestations are: fewer product varieties and low level. , The quality is unstable, the early failure rate is high, and the reliability is poor.
Stainless steel fasteners are the main basic products in the machinery industry. The development of the machinery industry also puts forward higher requirements for stainless steel fastener products. Luo Baihui believes that the current domestic supply of ordinary standard stainless steel fasteners has been oversupply, while high-grade stainless steel fasteners (high temperature, special-shaped, titanium-plastic composite, special performance stainless steel fasteners, etc.) are in short supply and rely on imports. The State Machinery Bureau lists "ordinary standard fasteners" as restricted development products, and "high-strength special-shaped fasteners" as currently encouraged development products. The use of high-strength stainless steel fasteners has gradually increased with the improvement of the country's industrialization level and technological progress.
