Intergranular corrosion of a martensitic stainless steel

Martensitic stainless steel (420B) microstructure show carbides precipitate at grain boundaries. Chromium, present in the matrix to guarantee corrosion resistance, is taken away to form chromium carbides. This causes a strong reduction in the corrosion resistance just near the carbides.┬áThis … Continue reading
