10、n turn,if permitted to reach the stainlesssteel surface,are possible to contribute to external stresscorrosion cracking(ESCC).Therefore,it is important to reducethe exposure of such insulating materials to water-solublecorrosive ion compounds at all stages of manufacture,handling,shipping,storage,an
