Quenching & Tempering Steel Bar Line

Quenching & Tempering Steel Bar Line with Induction Heating: Process Guide Quick Answer On a quenching and tempering steel bar line, each bar is induction heated to its austenitizing temperature, quenched to form martensite and then tempered to the target hardness. On HLQ lines, 42CrMo bars are quenched from 840–880 °C in oil or polymer … Read more

How to Select an Induction Quench and Temper Line

To select an induction quench and temper line, start from the workpiece range (diameter, length, weight, steel grade), the required throughput in tons per hour and the hardness and property targets. Then choose the frequency, power, quench system, tempering method and layout. For through heating, HLQ recommends 2–8 kHz for 20–50 mm bars and 0.5–2 … Read more
