摘要 研究了430铁素体不锈钢晶间腐蚀和表面"金粉"缺陷的关系。通过Gleeble 3800热模拟机模拟了不同工艺条件下的热轧实验,以及热轧后模拟卷取对430铁素体不锈钢晶间腐蚀敏感性产生的影响;采用双环-电化学动电位再活化(DL-EPR)法检测430铁素体不锈钢的晶间腐蚀。结果表明:430铁素体不锈钢在热轧时产生敏化,在酸洗过程中造成的晶间腐蚀,最终会导致冷轧后表面"金粉"缺陷的产生。Gleeble实验表明,最终变形温度为900~950℃,冷速为水冷条件下有利于避免晶间腐蚀的产生。模拟卷取实验表明,经过650~800℃的处理能够进一步避免和消除430铁素体不锈钢的晶间腐蚀敏感性。

Abstract:The relationship between the intergranular corrosion and "gold dust" defects on surfaces of 430 ferritic stainless steel was investigated. On the basis of the different hot rolling tests performed on Gleeble 3800 thermal mechanical simulation and simulated coiling test after deformation, a study was conducted in order to determine the effect of thermal processing on the intergranular corrosion of 430 ferritic stainless steel. The DL-EPR was introduced to measure the susceptibility to intergranular corrosion.The results showed that the 430 ferritic stainless steel sensitization happened in the process of hot rolling, then conduce intergranular corrosion during the pickling, eventually produced the "gold dust" defects after cold rolling. It is found that the intergranular corrosion sensitization could be effectively prevented with a combination of final rapid cooling (water cooling) at the final deformation temperature of 900-950℃.By the analysis of simulated coiling test results, the intergranular corrosion susceptibility of 430 ferritic stainless steel can be further avoided and eliminated by a treatment of 650-800℃.
