Oil quenching - tempering: A wire that is drawn to the finished size and quenched and tempered in a continuous furnace. The unwound wire is first heated to full austenitizing temperature in a continuous furnace and then quenched by oil bath Martensite, and then through the continuous furnace tempering, to obtain the expected strength and toughness. Oil quenching - tempering steel wire straightness is good, the uniformity of mechanical properties, made of components or components only after low temperature stress treatment that can be used directly.
