介绍用普碳钢经过冷拔、制钉、渗碳、淬火、稳定化处理、镀锌生产出特种钢钉的工艺方法。对特殊零件进行渗碳时，可以打破传统的渗碳工艺规范的某些要求，使密堆集小零件获得均匀适宜的渗碳层。该方法工艺简单，质量稳定，产量高，成本低。 Introduced with plain carbon steel after cold drawing, nail making, carburizing, quenching, stabilization, galvanized to produce special steel nails process. When carburizing special parts, certain requirements of the conventional carburizing process specification can be broken, so that the densely packed small parts can be uniformly carburized. The method has the advantages of simple process, stable quality, high output and low cost.
