The variation in mechanical properties after cold deformation (bending) of pipes is one of the interesting subjects in material science. One major quality the material should possess is high corrosion resistance after cold deformation. The study deals with the observation of pitting corrosion resistant property of cold deformed (bended) tubes of 316 type and 6Mo stainless steel. ASTM G48 and ASTM G61 test methods are followed as experimental procedure for the completion of this project. The Scanning Electron Microscope (SEM) is used for the examination of pitting corrosion after G48 Test. Similarly, the cyclic polarization graph is used for measuring the pitting and repassivation potential after G61 Test. The cold deformed and the straight parts of both 316SS and 6Mo were seen to be holding a similar corrosion resistant property. The weight loss per unit area was found to be similar after G48 test and the pitting and repassivation potential values were in a similar range. The hardness of bended parts for both 316SS and 6Mo are measured higher than the straight parts.
