摘要
本文研究了超级13Cr和15Cr马氏体不锈钢分别在120℃和95℃全程酸化(鲜酸+残酸)实验中的耐点蚀性能。结果表明:超级13Cr和15Cr不锈钢在120℃条件下的点蚀速率分别为1.59mm/a和1.35mm/a;在95℃条件下的点蚀速率分别为6.55mm/a和2.60mm/y;95℃条件下两种材质的点蚀速率高于120℃条件下的点蚀速率;在两种腐蚀条件下15Cr较13Cr表现出更优异的耐点蚀性能。
This paper studied the pitting corrosion resistance performance of super 13 Cr and 15 Cr stainless steel under the entire acidizing（fresh acid ＋ residual acid） experiment at 120℃ and 95℃.The results showed that pitting corrosion rates of super 13 Cr and 15 Cr stainless steel were 1.59 mm/a and 1.35mm/aat 120℃; The pitting corrosion rates of super 13 Cr and 15 Cr stainless steel were 6.5mm/a and 2.6mm/aat 95 ℃; The pitting corrosion rates of the two materialsat 95℃ were higher than pitting corrosion rates at 120℃;The pitting corrosion resistance of super 15 Cr was better than 13 Cr stainless steel in the two corrosion conditions.
