Abstract

The intergranular corrosion behavior of 430 ferritic stainless, with 0.025% up to 0.065% nitrogen contents, was studied by DL-EPR testing, SEM and EDS to elucidate the influence of nitrogen. The results indicated that, with the increase of the nitrogen content in the steel, the susceptibility to intergranular attack became more serious, when the nitrogen content increased up to 0.045wt.%, the tendency was no more obvious; The Ra values increased with the extension of sensitization time, low nitrogen content has a beneficial effect on inhibition of this trend; The precipitation of V(C, N) improved the intergranular corrosion resistance to some extent, especially in the stainless steels contained low nitrogen.
