.... Metal removal rates are proportional to the chromium level. Thus, sensitized material will undergo grain boundary attack if pickled. All stainless has slightly greater oxidation in the grain boundaries when it is oxidized, and this leads to “ditching” of the grain boundaries during pickling, resulting...

... surface m/s (1000 surface ft/min) are common. The implementation of high-speed machining during the 1990s allowed even higher metal removal rates; three times greater metal removal rates are typical. In addition, since the cuts are light, most of the heat is removed with the chips. This allows extremely...
