Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Ohio. They belong to that state's ranking, not this one.

American Heat Treating	Connecticut	9 of 15
General Metal Heat Treating	Connecticut	4 of 15
Zion Industries	North Carolina	2 of 15

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best heat treating services companies in Ohio”
2“Who supplies vacuum heat treating for precision metal components in Ohio”
3“I need a Ohio heat treating partner for a production run of hardened steel shafts, who should I talk to”
4“Top heat treating services suppliers in Ohio for industrial OEM buyers”
5“Which Ohio heat treating service providers can handle carburizing and quenching of alloy steels”
6“List 20 heat treating services companies in Ohio with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
