摘要
研究了ＳＡＦ２２０５双相不锈钢和尿素级３１６不锈钢对接焊热影响区在工业尿素合成介质中的耐蚀性．实验结果表明，焊接线能量对热影响区的耐蚀性有重要影响，腐蚀最重处是在距离熔合线３－６ｍｍ区域，局部腐蚀深度随线能量的增加而增大．ＳＡＦ２２０５不锈钢焊接线能量对热影响区腐蚀的敏感程度比３１６Ｌ不锈钢大．
The corrosion resistance of the heat-affected zone (HAZ) of butt-weld for duplex stainless steel SAF2205 and austenitic stainless steel 316L in urea media were studied. Experimental results revealed that welding linear energy (WLE) has important influence on the corrosion resistance of HAZ. A severe corrosion zone appeared at a distance of 3-6mm from melt run. The depth of local attack increased as increasing WLE. The corrosion of HAZ in the SAF2205 was found to be more susceptible to WLE that in 316L.
