   * "The surface of ferrous metal castings has a scale that is more difficult to machine than the metal below/​within. Some scale is more difficult to machine than others, depending on the foundry sand used, the casting process, the method of cleaning the casting, and the type of metal cast. Special electrochemical treatments sometimes can be used that almost entirely eliminate the effect of the scale on machining, although castings so treated are not frequently encountered. Usually, when casting scale is encountered,​ the cutting speed is reduced approximately 5 or 10%. Difficult-to-machine surface scale can also be encountered when machining hot-rolled or forged steel bars." (Machinery'​s Handbook, 28th Edition p. 979 of 3455)   * "The surface of ferrous metal castings has a scale that is more difficult to machine than the metal below/​within.
