Best method of Localized Heat Treating

2003

I am currently using natural gas jet heaters to locally heat treat a section of coil steel. We uncoil the material, pass the material through the heat treat station which hardens one edge (approximately to 1/8" from edge), then recoil the material. The material (either 1075 or 1095 Carbon Steel) varies in width from 1/2" to 4" and has a thickness of 0.020" to 0.060". We are looking at automating multiple processes, one of which is the heat treating portion. My question is this: Is this the best type of heat treat for the application? I have heard of others using induction heat, but do not know much about it.

Any help would be greatly appreciated.

Inductive heating would probably be the best option. It is capable of a very localized and a very high heat that is as controllable as a flame in its intensity.
