✦ Synopsis

The acidity of wood and its polyphenolic content are shown to be primary factors concerned in the corrosion of sawblade steels (Krilov 1985). Those polyphenolic compounds which possess two or three adjacent hydroxyl groups are particularly important because of their ability to form iron chelates. In this paper some fundamental aspects of chemical corrosion are discussed and a general reaction scheme is proposed for the corrosion of steel by polyphenolic compounds. The validity, of these assumptions is supported by experimental results. Better knowledge of steel corrosion chemistry should be of considerable practical benefit to both timber conversion and building industries.
