Decarburization is usually conducive to the improvement of the delayed failure performance, but the fatigue strength must be fully taken into account and the bolts should not trip or slide. The pre-annealing process for raw materials must pay strict attention to decarburization and carbon recharging, and carbon addition to the surface of threads is not allowed during final quenching and tempering.
Prior to cold drawing, the rod needs to be subjected to softening annealing or spheroidizing annealing. In order to prevent decarburization, a protective atmosphere is often used or charcoal is placed in the furnace. If the atmosphere in the furnace is not properly controlled or a special situation occurs, carbon addition will occur on the surface of the raw material. As the surface of the thread increases carbon, the strength increases and the plasticity decreases, resulting in delayed fracture.
