Effect of Heat Treatment on Corrosion Resistance of 0Cr18Ni9Ti Stainless Steels

0Cr18Ni9Ti stainless steels are used extremely broad, but the corrosion phenomena of 0Cr18Ni9Ti stainless steels will happen in its using because of various reasons. 0Cr18Ni9Ti stainless steels were taken with different process of heat treatment in order to change its corrosion resistance in this paper. The corrosion resistance performance of the samples was discussed by metallographic picture observation, weight-loss method and organizational analysis. The better heat treatment process was chosen, according to the contrast experiment method. The results indicate that the sample has the best corrosion resistance after 1040°C×1.5h solid solution and stabilization treatment of 890°C×2h. This study has certain positive meaning to improve the 0Cr18Ni9Ti stainless steel corrosion resistance.
