摘要：

现有文献资料上对410不锈钢锻后退火的工艺提法不同，为了确定适合的退火工艺，根据现有文献资料，选取不同参数进行试验，通过对硬度和金相组织的对比，确定了780 ℃退火、保温2.0～3.0 h、出炉后自然空冷的不完全退火工艺，并严格执行410不锈钢锻造工艺，控制终锻温度在900 ℃以上。该工艺在生产中进行了实践，结果证明，退火工艺达到了保证180～220 HBW的硬度范围、提高切削性能的预期。此不完全退火工艺与完全退火工艺相比，锻件的硬度合格率、机械加工性能和生产效率都得以提高，产品最终力学性能也得到了相应的提高，从而说明了该退火工艺具有较强的实用性和良好的经济效益。

The existing literature shows that annealing processes of stainless steel 410 forgings are different. In order to determine the suitable annealing process, according to the existing literature, the experiments with different parameters were carried out, and the incomplete annealing process with natural aircooled was determined at 780 ℃ for 2-3 hours by comparison of hardness and metallographic structure. However, the forging process of stainless steel 410 was strictly executed, and the final forging temperature was controlled above 900 ℃. Furthermore, the annealing process was practiced in the production process, and the results show that the annealing process can ensure hardness 180～220HBW as well as improve the expected performance of cutting. Comparing incomplete annealing process with the full annealing process, the qualified rate of the forging hardness, machining performance and production efficiency are improved, and the mechanical properties of the final product are also improved. Thus, the annealing process has strong practicability and good economic benefits.
