摘　　要：聚氯乙烯(PVC)在脱氯过程中会产生大量的HCl气体,而HCl具有很强的腐蚀性。对3种奥氏体不锈钢(00Cr17Ni14Mo3(316L)、0Cr18Ni9Ti(321)、1Cr18Ni9(302))进行抗HCl气体腐蚀实验,并对试样进行扫描电镜(SEM)和能谱(EDS)分析。结果表明:不锈钢316L的抗HCl气体的腐蚀性能最好,在本研究条件下,不锈钢316L最适合用来作PVC脱氯反应器的内衬。A great amount of HCl gas with strong corrosivity can be produced when polyvinyl chloride （PVC） is dechlorinated. Three kinds of austenitic stainless steel （00Cr17Ni14Mo3 （316L）, 0Cr18NigTi （321） and 1Cr18Ni9 （302）） which belong to HCl corrosion-resistance steels are researched in this paper. Steel samples were analyzed by sweep electron microscope （SEM） and energy dispersion spectrum （EDS）. The results showed that stainless steel 316L was the best one in corrosion-resistance property to HCl. Therefore, stainless steel 316L is the best material used as inner lining of dechlorination reactor.
