低铬铁素体不锈钢晶间腐蚀敏感性的测试方法及性能
Test Methods and Susceptibility of Low-Cr Ferritic Stainless Steel to lntergranular Corrosin
摘 要
研究了爆炸复合板复层06Cr13R低铬铁素体不锈钢的晶间腐蚀敏感性测试方法及性能。结果表明: 电化学动电位扫描法(双环EPR法)适合用于爆炸复合板复层06Cr13R低铬铁素体不锈钢晶间腐蚀敏感性的检测, 其试验结果与草酸电解侵蚀法对应较好；06Cr13R低铬铁素体不锈钢的晶间腐蚀敏感性与铬-镍奥氏体不锈钢不同, 其晶间腐蚀敏感性出现在910 ℃正火处理后, 甚至强制吹风急冷条件下也无法避免, 而经过800 ℃退火处理后, 其晶间腐蚀敏感性可减轻。

Abstract
The test methods and susceptibility of explosion composite plate compound layer 06Cr13R low-Cr ferritic stainless steel to intergranular corrosion were studied. The results show that the double-loop EPR method was appropriate for evaluating the susceptibility of 06Cr13R low-Cr ferritic stainless steel to intergranular corrosion, which was consistent with the test results of oxalic acid electrdysis erosion method. The characteristics of intergranular corrosion of 06Cr13R low-Cr ferritic stainless steel was different from Cr-Ni austentic stainless steels. The susceptibility to intergranular corrosion occured after the normalizing treatment at 910 ℃, even forced air cooling, but it was alleviated after the annealing treatment at 800 ℃.
