Title:
Titanium Carbides as a Cause of Knife-Line Corrosion,

Abstract:
1Kh18N9T 0.08 percent C, 1.18 percent Mn, 18.24 percent Cr, 9.25 percent Ni, 0.21 percent Mo, 0.80 percent Ti steel was subjected to microscopic and x-ray examination to determine the effect of titanium carbide on knife-line corrosion. By structural analysis of overheated titanium-stabilized steels and by oxidation of titanium carbides at potentials corresponding to the corrosion of these steels in nitric acid, it was shown that the dendritic titanium carbides precipitated in grain boundaries after overheating are one of the main causes of knife-line corrosion. Heat-treatment to eliminate the knife-line corrosion had only limited effect.
