在含氯离子的水溶液中,奥氏体不锈钢容易发生应力腐蚀(SCC)、孔蚀等局部腐蚀。许多研究表明,在生产工艺许可的条件下,采用缓蚀剂,改变环境条件以控制奥氏体不锈钢的局部腐蚀是可能的。实验用1.5mm厚冷轧1Cr18Ni9Ti(AISI321)不锈钢(321 S.S.)板,加工成70×12×1.5mm的试样,在600±10℃的马弗炉中敏化24小时,用砂纸打磨,一次成型弯成内径
In chloride-containing aqueous solution, austenitic stainless steel is susceptible to localized corrosion such as stress corrosion (SCC) and pitting corrosion. Numerous studies have shown that it is possible to use corrosion inhibitors and local environmental conditions to control localized corrosion of austenitic stainless steels, as permitted by the manufacturing process. Experimental A 1.5 mm thick cold-rolled 1Cr18Ni9Ti (AISI321) stainless steel (321 SS) plate was processed into a 70 x 12 x 1.5 mm specimen and sensitized in a muffle furnace at 600 ± 10 ° C for 24 hours, sanded with sandpaper Bending into the inner diameter
