Chinese fastener companies now have no new advantages and are the bottleneck restricting the power of fasteners. At present, most of the fastener enterprises in our country attach importance to cold heading, cold extrusion and cold punching. Engineers are skilled in mold design, often re-cold processing, light heat treatment, some companies rely on external heat treatment to ensure the shipment. Can not guarantee the quality of fasteners, in the long run, relying on external processing, is a direct impact on the innovation and development of fasteners.
However, the importance of current heat treatment in our country and some companies do not get due attention, in the relevant scientific research plans, development plans, project guidelines and discipline settings, or the lack of heat treatment content, this situation needs to be reversed. At present, taking measures to promote heat treatment of fasteners at different levels is of great significance for realizing the transition from a fastener manufacturing country to a fastener manufacturing nation.
Fasteners play a role in the connection, positioning and sealing of mechanical components, among which the maximum amount of bolts is used. High-strength bolts have a total of five performance levels, namely 8.8, 9.8, 10.9, 12..9 and 12..9. According to technical requirements, these five grade bolts must be heat treated. Heat treatment is to improve the overall mechanical properties of the bolt to meet the product's specified tensile strength and yield ratio; the choice of materials is the basis for quality assurance. Heat treatment technology is crucial for high-strength bolts, especially its intrinsic quality.
