What is a Mill Scale? Definition from Corrosionpedia

Jun 23, 2014 Mill scale is a severe nuisance in steel processing. Any coating applied on top of the scale goes to waste. This happens because the steel can be laden with moisture when air gets into it. Electrochemically, mill scale is cathodic compared to steel, so any kind of breakage in the scale could lead to accelerated corrosion in the steel at the

What exactly is Mill Scale and what is done about it

Mill scale immediately starts at the steel making stage of casting hot metal steel grades and steel alloys when the metal is in a liquid stage. The mill scale chemistry will be the exact makeup of the steel and/or steel alloys being made. It is the outer skin of the casting and is formed by the rusting of the iron as it is exposed to the

Jan 21, 2019 Mill scale is less reactive than the steel surface it covers, acting as a cathode to the more reactive material underneath. Once the scale coating breaks (which occurs easily) and moisture comes through, the presence of the scale iron oxide accelerates the corrosion process at the breakage point.
