For conventional machining, tungsten carbide tools are most commonly used, although some softer alloys or alloys in an annealed state may be machined with difficulty using highspeed steel. Cubic boron nitride tools are commonly used...

... strength, and/or rigidity of the toolholder are also important concerns. As noted previously, carbide tools are usually used in turning heat-resistant alloys, although ceramic, coated carbide, cubic boron nitride, and HSS tools are also used. A C-2 grade is frequently selected for roughing. A C-3 grade...

.... Only diamond and cubic boron nitride were better. Silicon nitride can be made by a number of techniques, but one is nitriding shapes made from silicon powder compacts. A positive feature of silicon nitride is its 60% lower density than steel ( Fig. 10.8 ), which, by calculations, reduces...

... approach, as characterized by alloy 430, is to permit chromium carbides and nitrides to form but then to perform a subcritical anneal to rehomogenize the chromium and coarsen the precipitates so that they have only a small negative effect on mechanical properties.
