Mill scale - Wikipedia

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.

Millscale - an overview ScienceDirect Topics

R. Lambourne, in Paint and Surface Coatings (Second Edition), 1999 13.3 Surface preparation. To obtain satisfactory performance from a paint system it is essential for millscale to be removed from the surface of the steel. Not only does it contribute directly to corrosion, but it will eventually become detached from the steel surface and is therefore an unsatisfactory substrate for painting.

Factors for Selecting the Right Stick Electrode

To achieve the best results, you should always remove excessive mill scale, rust, moisture, paint and grease. Clean base metals help prevent porosity and increase travel speeds.
