Title: Improvement of Corrosion Resistance of Interstitial Free Steel by Pickling
Abstract: he effect of pickling on thecorrosion resistance of interstitial free steel ( IF steel) was studiedby using energy dispersive X-ray analysis, electrochemical test,corrosion test at constant temperature and humidity, and alterna-ting damp-and-hot corrosion test. It has been found that the con-tent of manganese on the surface of IF steel is reduced after beingdipped in 5 % hydrochloric acid bath, and hence the corrosion re-sistance of the IF steel is increased. The reason might be thatetching in hydrochloric acid contributed to eliminaton of the en-richment of manganese on surface of IF the steel, leading to in-creasing corrosion resistance of the steel.
