摘要: 为了改善441不锈钢管冷弯部位的胀形性能，避免冷弯管的胀形开裂。本文研究441不锈钢冷弯管的退火工艺参数对硬度、伸长率和强度的影响，获得了441不锈钢冷弯管的最佳退火工艺。低于或高于850℃退火，材料的硬度都升高，伸长率和强度都降低；保温时间的延长只能降低硬度，对伸长率和强度没有帮助。退火后慢冷(空冷)导致更多的第二相析出，与水冷相比伸长率较低。
Abstract: In this paper, in order to improve the bulging performance of 441 stainless steel tube and avoid the cold tube bulging cracking, the effect of annealing process parameters on hardness, elongation and strength of 441 stainless steel cold bending pipe have been studied. The best annealing process of 441 stainless steel cold bending pipe have been obtained. Lower or higher than 850℃, hardness of materials are increases, elongation and strength are reduced. Insulation time can only reduce the hardness and do not have any effect on elongation and strength. Slow cooling (air cooling) after annealing results in more second phase precipitation, which decrease the elongation compared to water cooling.
