WebMay 29, 2024 · Which is a Graphitising element? Graphitisation has only been found in simple carbon and C:Mo steels. Steels containing about 0.5% Cr or more do not suffer this type of degradation, presumably because chromium forms more stable carbides than do iron and molybdenum. Graphitisation is also retarded by the elements Mn, Mo, Ti and V.
