摘要
31 6L不锈钢是一种耐蚀性能很好的材料 ,但是安装质量特别是焊接质量对其应力腐蚀破裂 (SCC)性能有很大的影响 ,针对抚顺石化多次沿焊接热影响区 (HAZ)发生断裂事故的一套 3 1 6L不锈钢设备进行失效分析 ,认为该设备的断裂属于SCC ,焊接接头质量差是造成断裂的根本原因。
L stainless steel is a material with perfect erosion resistance. The installation quality and weld quality have substantial effect on SCC resistance. A failure analysis on a 316L stainless steel facility which cracked frequently along HAZ. It was suggested that the failure was SCC and that bad weld caused the crack.
