AbstractThe corrosion behaViors of stainless steel tubewater treatment agent and acid solution have been studiedThe
major causes of pitting in the 3()4 stainless steel tubes for condenser are that the quality of the stainless steel tube is unsatis
factory and the acid solution is unsuitable Weight loss measurement can not evaluate the coosion behavior of acid solution
for stainless steel It should be specined in any contmct to test the weld quality of stairIless steel tube according to the item
S7 in ASTM A249
