Fundamentals of Rockwell Hardness Testing

Selecting the Proper Scale In many instances Rockwell hardness tolerances are indicated on drawings. At times, however, the Rockwell scale must be selected to suit a given set of circumstances. Many Rockwell applications are covered by the B and C scales, which are used for testing steel and copper as well as their alloys.

What is a Mill Scale? - Definition from Corrosionpedia

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 point of breakage.
