The Effect of PWHT on Electrochemical Behaviour of AISI 316L Weld Metal
Chemical and Biochemical Engineering Quarterly, 2008 The subject of investigation was the corrosion behaviour of AISI 316L austenitic stainless steel weld metal as dependent on a protective passive film formed on the steel surface following exposure to w = 3.5 % NaCl. The corrosion properties were examined before PWHT and after it by means of cyclic polarization, electrochemical impedance spectroscopy ...
