pearlite is obtained by use of only one water cooling step
followed by one air cooling step. Thus, the heating of the
surface of the wire by heat from the core of the wire
discussed by Hoffmann does not appear to be significant in the
Vanneste ‘472 process. Moreover, in Hoffmann’s figure 1 the
transformation to pearlite takes place in zone I (col. 3,
lines 3-4), which is after the water cooling steps (col. 3,
lines 36-50; figure 1). The examiner has not explained why
Hoffmann would have fairly suggested, to one of ordinary skill
in the art, use of a water cooling step during the
transformation stage.
