The superior performance of Qiǎnshèng's disc nut begins with the careful selection of raw materials, primarily sourced from reputable domestic steel mills that supply high-grade carbon steel, alloy steel, and stainless steel in various compositions. For standard disc nut applications, the company predominantly uses medium-carbon steel grades such as 45# steel and 40Cr, which offer an excellent balance of strength, toughness, and machinability for general-purpose fastening tasks. For projects requiring enhanced corrosion resistance or high-temperature performance, stainless steel grades like 304, 316, and 17-4PH are utilized, providing extended service life in harsh chemical or marine environments. Each incoming coil or bar of raw material undergoes rigorous chemical analysis and mechanical testing to verify composition, hardness, and tensile strength before being approved for production. The material traceability system at Qiǎnshèng ensures that every disc nut can be traced back to its original heat number and supplier, which is critical for quality assurance and regulatory compliance in sensitive industries. This meticulous approach to material selection guarantees that the finished disc nut possesses the required mechanical properties to withstand real-world operational stresses without premature failure or deformation.

The manufacturing process for the disc nut at Qiǎnshèng integrates cold forging, machining, heat treatment, and surface finishing in a controlled, sequential workflow that maximizes consistency and dimensional accuracy. Cold forging is employed for initial shaping of the nut blank, which not only improves material utilization by reducing waste but also enhances the grain flow structure of the metal for superior strength characteristics. Following the forging stage, precision CNC lathes and thread rolling machines perform the final machining operations to achieve exact thread profiles, chamfer dimensions, and surface roughness values as specified by the client. Heat treatment is then conducted in automated continuous furnaces with precise temperature control and atmosphere regulation to achieve the desired hardness range, typically between HRC 22 and HRC 32 for hardened disc nut grades, depending on the application requirements. Surface finishing processes such as phosphating, black oxide, or zinc flake coating are applied to improve corrosion resistance, reduce friction during installation, and provide a consistent aesthetic appearance across the entire production batch. The entire manufacturing workflow is documented through digital records that capture process parameters, inspection results, and operator details to ensure full traceability and facilitate continuous improvement initiatives.
