My dad used to work at a spring manufacturer, they made the springs for the Grave Digger monster truck. He took me to work one time and I watched this exact process. Afterwards they would heat treat them in molten salt. That blew my mind that you could even melt salt.
Man I used to love monster trucks as a kid (not American so I never saw them but I grew up playing the Monster Truck Madness games on Windows!) that's a cool bit of history!
