...-hardening with induction are the same as for the other surface-hardening techniques. This would include the ability to harden lower hardenability ferrous materials and to have less distortion from processing. The pattern of heating obtained by induction is determined by the (a) shape of the induction...

... and quenching. Carburizing is discussed in greater detail in Chapter 8, “Case Hardening of Steel.” Carbonitriding Carbonitriding is a case-hardening process in which a ferrous material (most often a low-carbon grade of steel) is heated above the transformation temperature in a gaseous atmosphere...
