Induction forging is a process where a precisely controlled magnetic field is used to heat metal to be formed into shape using pressure applied by an impact hammer or press. Induction generates an electromagnetic field in a work coil that induces currents in the conductive material of a workpiece placed within or near the coil. Friction from these currents elevates the temperature of the workpiece prior to forging. [Can we help?](https://www.ambrell.com/contact-us-request-process?lead_origin=forging&linked_from=Forging%20[EN]&appnote_title=none) ## Benefits of Forging with Induction A superior and flame-free alternative to furnace heating, induction heating provides faster, more efficient heat in forging applications. The process relies on electrical currents to produce heat within the part that remains confined to precisely targeted areas. High power density means extremely rapid heating, with exacting control over the heated area.

Applications where material failure occurs because of cracking would benefit from hot forging. Reduction in press forces are also beneficial using hot forging. Consistent thruput, efficiency of the process and reduced scale formation are a few benefits of induction forging. The induction forging process produces heat within the part, but the heat is generated near the outside surface and will take time to conduct to the center of the part. Typically, bar-ends up to 20 mm in diameter through-heat in less than 10 seconds, whereas a 75 mm diameter bar will take 150 seconds to heat to the center. Hot forging is when a part is heated above the material recrystallization temperature before forging, typically 1100 °C (2012°F). Hot forging allows a part to be formed with less pressure, creating finished parts with reduced residual stress that are easier to machine or heat treat. ## forging Resources ##### Select an option below: - Forging Note Volume Offer - Featured Video - Other Resources ## 18-page induction forging packet [](https://www.ambrell.com/appnote-request?lead_origin=forging&appnote_filename=Forging%20Applications%20Packet%201&appnote_title=Forging%20Applications%20Packet%201&narration=We%20have%20combined%20our%20'Induction%20Heating%20for%20Forging'%20brochure%20and%205%20popular%20application%20notes%20to%20help%20you%20understand%20the%20many%20ways%20induction%20heating%20can%20improve%20your%20forging%20processes.&linked_from=appnote%20cards)We have combined our 'Induction Heating for Forging' brochure and 5 popular application notes to help you understand the many ways induction heating can improve your forging processes.

Induction forging is a process where a precisely controlled magnetic field is used to heat metal to be formed into shape using pressure applied by an impact hammer or press. Induction generates an electromagnetic field in a work coil that induces currents in the conductive material of a workpiece placed within or near the coil. Friction from these currents elevates the temperature of the workpiece prior to forging. Benefits of Forging with Induction A superior and flame-free alternative to furnace heating, induction heating provides faster, more efficient heat in forging applications. The process relies on electrical currents to produce heat within the part that remains confined to precisely targeted areas. High power density means extremely rapid heating, with exacting control over the heated area.

Hot forging is when a part is heated above the material recrystallization temperature before forging, typically 1100 °C (2012°F). Hot forging allows a part to be formed with less pressure, creating finished parts with reduced residual stress that are easier to machine or heat treat. What is through-heating? ### What is through-heating? The induction forging process produces heat within the part, but the heat is generated near the outside surface and will take time to conduct to the center of the part. Typically, bar-ends up to 20 mm in diameter through-heat in less than 10 seconds, whereas a 75 mm diameter bar will take 150 seconds to heat to the center.
