The behavior of non-sensitized intergranular corrosion (IGC) for urea grade316L stainless steel (SS) was studied by using the method of the potentiostatic etching in thetranspassive potential region and the metallograph.
采用恒电位浸蚀法配合以金相方法,研究了尿素级316L不锈钢非敏化晶间腐蚀的发展规律,比较了不同浸蚀介质、控制电位和浸蚀时间等因素的影响,结果表明:过钝化区恒电位浸蚀法可以快速、灵敏地检测奥氏体不锈钢的非敏化晶间腐蚀敏感性,使用超低磷、硅不锈钢可以减轻或消除非敏化晶间腐蚀,实验推荐下列二种检验操作条件:(1)10％草酸+0。
The corrosion of X2Mod lining of urea tower was caused by the lean chromium in the heat affected zone, which was normally called the sensitized intergranular corrosion.
尿素合成塔X2Mod衬里腐蚀是由于热影响区贫铬引起的 ,即通常所说敏化态晶间腐蚀。
Whereas the impurities like P and Si etc in the steel were the main culprits for the non-sensitized intergranular corrosion.
而钢中含有P、Si等杂质则是引起非敏化态晶间腐蚀的主要原因。
The non-sensitized IGC of austenitic SS may be lightened by using high purity SS.
使用高纯不锈钢可以减轻非敏化态晶间腐蚀。
