通过各项试验及数据,研究了热处理工艺对SA182-F316LN钢组织及力学性能的影响。在此基础上得到了该钢生产制造的固溶热处理工艺参数及锻造热处理参数。通过实践证明,该工艺合理可行,并且固溶后,该钢综合性能要高于锻造状态的性能参数,为以后同类实验提供了借鉴。 Through various experiments and data, the effect of heat treatment on the microstructure and mechanical properties of SA182-F316LN steel was studied. On this basis, the solid solution heat treatment process parameters and forging heat treatment parameters of the steel produced are obtained. The practice proves that the process is reasonable and feasible, and after the solution treatment, the comprehensive performance of the steel is higher than that of the forging state, which provides a reference for the similar experiments in the future.
