Heat Treat Radio #133: Process Qualification & Recipe Development in Vacuum Carburizing

Heat Treat Radio host Heather Falcone and guest Vincent Lelong, Senior Synergy Center Manager and Metallurgist at ECM USA, explore the realities of process qualification and recipe development, and in modern heat treating. Vincent shares decades of experience developing vacuum carburizing processes for automotive, aerospace, and high-volume manufacturing applications. Together, they discuss how heat treaters can balance metallurgy, fixturing, quench strategy, and production demands to achieve repeatable results. From practical troubleshooting insights to the evolution of vacuum carburizing technology, this conversation offers a grounded look at what it takes to optimize heat treating.
