• (p. pr. & vb. n.) of Patent
A heat treatment applied to medium and high-carbon steel prior to cold drawing to wire. The treatment involves austenitization followed by isothermal transformation at a temperature that produces a microstructure of very fine pearlite.Treatment of steel, usually in wire form, in which the metal is gradually heated to about 1830 (degrees) F., with subsequent colling, usually in air, in a bath of molten lead, or in a fused salt mixture held between 800 (degrees) F. and 1050 (degrees) F.
