​​Since 1999 “The Monty” has been publishing annually a list of the largest commercial heat treaters in North America based upon annual sales, our 2021 list can be found at https://themonty.com/project/50-largest-north-american-commercial-heat-treats-2021-2/ This year readers will see we became much more ambitious and expanded the list to the 50 largest.
