The linear polarization, polarization resistance, threepoint and CORFIT method have been used to determine polarization resistance values for 4130 Steel in inhibited HCl. From the three‐point and the CORFIT method the corrosion current and the Tafel slopes are obtained directly. A comparison of the results obtained by the four methods and an application to on‐line monitoring of inhibitor levels in pickling baths are given.
