Ti-stabilised interstitial free (IF) steels designed for enamelling applications contain higher levels of C, N, S and Ti than conventional deep drawing IF steels, e.g. for automotive applications. Consequently they contain a sufficient amount of hydrogen traps, which are essential to avoid the formation of fish scale defects during enamelling. A large amount of precipitates is however known to have a detrimental effect on the mechanical properties. The possibility of adding Ti-oxides as an alternative type of 'precipitate' and thus keeping the S and C-content of the IF steel low, was investigated. The present paper reviews the results of the investigation of the microstructure, the mechanical and the enamelling properties of a Ti-deoxidised laboratory cast IF steel with low C, N and S-content. The composition, morphology and size distribution of the inclusions and precipitates were evaluated by scanning electron microscopy at all stages of the laboratory processing.
