Abstract
The environmental concerns brought during pickling process of stainless steel in HNO3-containing acids need urgent attention. Choosing the hydrochloric acid pickling process as study object, this paper conducted a systematic study of the effect of temperature on the electrochemical behavior of stainless steel in hydrochloric acid solution. Research indicated that as temperature rose, the corrosion potential of 430SS in hydrochloric acid solution moved to positive direction with band to a narrow 0.1V. Meanwhile, the current intensity increased which indicated the acceleration of corrosion rate. In addition, the anode Tafel slope increased firstly and decreased later while the cathode Tafel slope increased slightly.
