The effect of Nb and heat treatment on the corrosion behavior of ferritic stainless steel in acid environments

The corrosion properties of ferritic stainless steel with admixtures of 0.5, 1.0, and 3.0 wt.% Nb are studied in 0.1M H2SO4 and 0.3M HCl solutions. The results obtained by the impedance and mass-loss methods demonstrate that the procedure of alloying with niobium and diffusion treatment positively affect the corrosion resistance of steel in these solutions. © 2008 Springer Science+Business Media, Inc.Firat ÜniversitesiAcknowledgement.
