摘要
通过对2Cr13不锈钢进行不同的热处理试验,并对其组织及力学性能进行了分析。结果表明:经淬火+回火的2Cr13不锈钢组织为回火索氏体,其拉伸强度、硬度随回火温度的升高而降低,伸长率及冲击韧性随回火温度的升高而提高。结合航空新零件的设计需求,推荐2Cr13不锈钢新零件的热处理制度为1 040℃/40 min淬火+580~600℃/60 min回火。
The microstructure and mechanical properties of 2Cr13 stainless steel were analyzed for different heat treatment tests. The results show that the microstructure of 2Cr13 stainless steel after being quenched and high temperature tempered is the tempered sorbite, and its strength and hardness decrease, while the elongation and impact performance increase with the increase of tempering temperature. In combination with the high standard requirements of aviation parts, the heat treatment system of 2Cr13 stainless steel is recommended to be quenched at 1 040 ℃ and tempered at 580 ℃ to 600 ℃.
