The Monty’s 50 Largest North American Commercial Heat Treats 2021
Since 1999 “The Monty” has been publishing annually a list of the largest commercial heat treaters in North America based upon annual sales, our 2020 list can be found at http://www.themonty.com/
- The pandemic has wreaked such havoc on the heat treating industry that it is difficult to know whether to use 2019 sales figures, 2020 or estimated 2021 figures since the past year and a half have been (hopefully) a temporary aberration. In the end we used a combination of sales figures from the past 3 years on the basis that our interest lies more in the relative ranking of each company as opposed to exact sales figures.
- While the pandemic affected most companies on our list the pain was by no means evenly distributed. Hardest hit were those companies almost exclusively tied to the aerospace industry while firms specalizing in the medical industry saw little change and heat treaters related to the firearms business couldn’t keep up with demand.
- Automotive heat treating has been a roller coaster for the past 2 years-the largest roller coaster you can imagine. While demand dropped substantially in April of 2020 it came roaring back to life later on in the year, only to be sidetracked by the “chip” shortage for the past 8 months. Our prediction is that when the chip shortage is resolved those doing heat treating of automotive components will witness unprecedented demand.
- We would estimate that on average most firms saw their sales drop 10% in 2020, most are now slowly recouping these losses.
- The vast bulk of companies on this list are privately held which means exact sales figures can be difficult to find. So while we are quite proud of our efforts and consider this list to be the most accurate available anywhere we do not for a second claim that it is 100% correct.
- Over the years some readers have pointed out that our rankings are not always in line with MTI figures (Metal Treating Institute is the largest organization of commercial heat treaters in North America and they rank their members in each geographic region). We would concur with this for two reasons. The first is that not all commercial heat treaters belong to MTI which “skews” the numbers. For instance some of the largest commercial heat treater on the continent do not belong, this includes Bodycote, Woodworth and Advanced Heat Treat Corp. Second MTI tracks members in a particular region. For instance Specialty Steel Treating does not rank as the largest in Michigan which is where they are headquartered but when you factor in their facility in CT (a different region for MTI) the overall picture changes.
- We are always asked where the information for our rankings comes from, a very fair question. The largest on our list, Bodycote is a publicly traded company and sales figure are freely available. Solar Atmospheres, #6 on our list is very open and said that we could post their sales figures, Most of the companies on this list did share sales figures with us on the basis that they not be printed, a very reasonable request. Further verification came from knowing the number of locations, the physical size of each, number of employees and the processes each offers.
- We appreciate the help and guidance everybody provided us with.
- All figures quoted are in US Funds.
Without a shadow of a doubt UK based Bodycote is the largest North American commercial heat treater and indeed the largest globally. Want to know exactly what the company’s sales are? As a publicly traded company their financial results are easily found at

The answer was “they are yours now” and thus one of the oldest commercial heat treaters in the USA was born. Akron is still a family owned business and offers a very wide variety of heat treating.
#49 Euclid Heat Treating, Euclid, Ohio
As are so many commercial heat treaters in North America, Euclid Heat Treat is another family owned business in this case the Vanas family. “The Monty Team” has had the opportunity to visit this facility a number of times over the years and have always been impressed with the variety of processes the company offers. “The Euclid Heat Treating Company was established in 1946 in a garage building at 1408 E. 222nd St. with salt furnaces and open fired furnaces. Since our inception we have expanded to include endothermic atmosphere furnaces, an entire building devoted to induction hardening, an array of vacuum furnaces including a vacuum oil quench and two 10 bar vacuum furnaces, pit furnaces, nitriding equipment and much more.”
#50 CRIO, Mexico
Commercial heat treater Crio is the third commercial heat treater in Mexico to make our list. The company founded their first location in Queretaro, Mexico in 2004 and since that time it has never looked back. CRIO now has 3 locations in Mexico which feature batch IQ furnaces, car bottoms, rotary hearth furnaces and press quenching systems. While the company does do a reasonable amount of aerospace work the backbone of the company is automotive work which means that the company achieved CQI-9 certification a number of years back.
