Abstract
As in parent patent patenting steel wire is carried out by heating to form austenite and isothermally quenching to obtain pearlite. In the addition, the isothermal quenching occurs in three successive phases: (a) the outer layer of the wire is cooled below the temp. of the nose of the time-temp. -transformation curve (TTT); (b) the outer layer is reheated by the heat contained in the core of the wire to a uniform temp. near to that of the nose of the TTT curve, before transformation is complete; nc) the uniform temp. is maintained at least until the complete transfer of austenite into ferrite and cementite. The new process avoids the disadvantages of known processes and suitable e.g. for wire 1-30 mm dia.
