  • 1.  Induction Heat Treatment Testing Lab

    Posted 26 days ago

    We process our steel by induction heat treatment and then use a polymer based quenchant. The induction heat process is very short at approximately 7 to 9 seconds max. We need to quench very quickly from the heat treatment area to our quench tanks with a travel time of 1 to 2 seconds max. We are looking to a lab that is familiar with induction heat treatment and rapid quenching to validate parts on a as need basis. We have used some mechanical testing labs in the past but their knowledge on induction heat treatment is usually limited. So, I am reaching out to others who perform induction heat treatment and quenching to maybe steer us to a lab that has knowledge in our specific field of heat treatment.

    Hey Heat Treat community - quick question for those with induction experience.

    Are there labs you would recommend that have hands-on experience with induction heat treatment and rapid polymer quenching?

    The best labs for this are internal as the induction process often requires development. Most labs can do the prep. Some guidance on evaluation of incipient melting, case-core transition microstructures and other desirable and undesirable features can make any capable lab proficient. Some internal labs do outside work. Boeing Technology Services can get work into Boeing labs. Boeing Portland lab has extensive induction experience.

    I would reach out to the supplier of your induction equipment first.  A few months ago there was a webinar on design of induction coils that was presented by Inductotherm.   I think the Webinar was held on August 5th, but can't find the link.  They showed finite element models (generated from COMSOL Multiphysics) that predicted the temperature distribution in the part.   It would seem that one of the main issues is understanding the temperatures within the part prior to quenching.
