One of the largest commercial heat treaters in North America as rated by “The Monty Heat Treat News” is the Stack Metallurgical Group headquartered in Portland, Oregon, USA (find our where they rank at https://themonty.com/project/50-largest-north-american-commercialheat-treats-2021-2/ ). Stack maintains impeccable facilities which features some of the latest and greatest heat treat technologies available. To give you an example these two very large bottom loading vacuum furnaces were added to the Portland facility just a few short years ago.

We now have word that the company  continues to invest and recently ordered a brand new 6 bar quenching, Turbotreater horizontal vacuum furnace from Ipsen which features an all metal hot zone. The furnace which is expected to arrive in June of this year represents a very substantial financial investment.
