High strength fasteners are conditioned according to technical requirements. Heat treatment quenching and tempering is to improve the comprehensive mechanical properties of fasteners to meet the required tensile strength and yield strength ratio of products. Heat treatment process has a vital impact on the internal quality of high-strength fasteners, especially its internal quality. Therefore, in [...]
Fastener Technology: Hot rolled- spheroidizing annealing- mechanical descaling- Pickling- cold drawing- cold forging- thread processing- heat treatment- Inspection. In the fabrication of fasteners, it is important to select the correct fastener materials, because the performance of fasteners is closely related to their materials. If the material selection is improper or incorrect, it may cause the [...]
