What is Intergranular Corrosion?
Intergranular attack is caused by the formation of chromium carbides (Fe,Cr)23C6 at grain boundaries, reducing the chromium content and the stability of the passive layer on stainless steels. This type of corrosion was previously a potential risk for stainless steel because of its high carbon content. However, with modern steel making methods, it has become [...]
