Corrosion of Stainless Steels in Melting Aluminum Alloy

The corrosion resistance of 0Cr25Ni20 steel and 0Cr18Ni9Ti steel which have excellent anti-corrosion performance in normal media were studied in melting aluminum solution. The results show that the corrosion process is controlled by the grouth of corrosion layer and complies with the parabolic rule. The corrosion resistance of 0Cr25Ni20 steel is superior to that of 0Cr18Ni9Ti steel.
