Induction hardening - Wikipedia

Induction hardening is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without

Heat treatment- Maschinenfabrik ALFING KESSLER GmbH

HEAT TREATMENT. Going beyond the actual forging process, the subsequent tempering and stress relieving performed on the crankshaft forging is decisive in terms of quality. For the purpose of tempering, the forgings are heated in bogie hearth furnaces. The temperature must therefore be above the limit for structural

Heat-treatment of crankshafts | High Power Media

Aug 14, 2009 If one was to specify a high hardness, requiring a low tempering temperature, it may be that the core material would be softened by the nitriding treatment. This effect can be mitigated by careful choice of alloy if high core strength is felt to be a requirement. However, it is quite common for crankshaft blanks to

Hardening with induction heating - EFD Induction

The main benefit of induction heating for hardening is that it takes just a few seconds. In a furnace, the same process can take hours or even days. How is that possible? The answer is that induction is phenomenal at generating heat fast. This, in turn, means you can integrate hardening in the production process. Hardening

State-of-the-art induction technology for crankshaft hardening plants

Along with this, torsional and flexural fatigue appears and demands a special heat treatment process.The induction hardening with a rotating crankshaft has mostly replaced competitive methods and provides the engine builders with a flexible process stages: 1) induction heating, and 2) quenching with a cooling medium.
