The Monty’s 50 Largest North American Commercial Heat Treats 2022
Since 1999 “The Monty Heat Treat News” has been putting together a list of the largest commercial heat treaters in North America based on annual sales. We are now very proud to present to you the list of the 50 largest commercial heat treaters in 2022, a list which we believe to be the most complete in the world.
- Rankings are based upon anticipated sales for the calendar year of 2022.
- While the turmoil of the past two years 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 specializing 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 ride for the past 2 years and the ride isn’t over. Those firms concentrating on this market segment have found sales going from record highs to record lows in just a few months.
- The oil and gas industry has seen a tremendous upside in 2022 and the result is that there are now more commercial heat treaters in Texas on our list than in 2021.
- We would estimate that on average most firms see their anticipated sales for 2022 increasing anywhere from 5% to 7 ½%.
- 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. 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 https://www.bodycote.com/
For the purposes of this report we are only looking at Bodycote’s North American sales and operations. The company reported 2021 sales in North American to be $300 million USD, with 72 plants in the USA, 3 in Canada and 4 in Mexico. We are not privy to anticipated sales in 2022, however we would assume there will be some increase.
#2 Aalberts Industries
Aalberts N.V. is a public company with its global HQ in the Netherlands. For years, Aalberts Surface Technologies has been the second largest commercial heat treater in Europe (previously under the name Hauck). In a relatively short period of time Aalberts went from a small player in the North American commercial heat treat industry to the second largest. This was achieved largely through acquisitions which over the years have included Premier Thermal, Applied Process, Alfe and several others. Incidentally if we put together a list of the largest commercial heat treaters in the world Aalberts would be the second largest.
Founded in 1943, Paulo is the largest privately held provider of thermal processing and metal finishing solutions in North America. Headquartered in St. Louis, Paulo operates six divisions servicing the Midwest, Great Lakes, and Southeast regions of the United States and northern Mexico. Paulo has been family owned and operated since the beginning, now the fourth generation carry on the business Ben and Pauline Rassieur started 77 years ago. The processes offered by Paulo cover austempering in mesh belt furnaces, Hot Isostatic Pressing, carburizing, nitriding, vacuum, brazing, zinc plating and black oxide to name a few. What makes Paulo unique to some extent is that the company has built in redundancy for most of their processes-if for some reason a process is not available at one particular location it can be quickly and competently shifted to another location. Paulo: Thermal Processing. Brazing. Heat Treating. Metal Finishing.
#4 Woodworth Heat Treating
The fourth largest North American commercial heat treater on our list is a company which operates 4 facility in two countries and specializes in large volume automotive work. “Woodworth Inc. provides a wide range of heat treatment services through our four facilities.

Woodworth Inc. has installed capacity to run 16 million + rotors per year. (2.2 million Lbs / Day).” Woodworth is similar to many heat treaters on our list in that they are almost exclusively dedicated to the automotive industry, albeit on a very large scale.
#5 Bluewater Thermal Solutions
“Bluewater Thermal Solutions operates 12 different heat treatment and brazing facilities in the United States and Canada and this makes us one of the largest heat treating and brazing companies in North America. Each location has different capabilities and equipment that allows them to offer specialized different types of processing required by their local markets. Bluewater provides thermal processing and metal joining to over 2,000 customers. In addition to specialty heat treatments and brazing, most of Bluewater’s locations offer traditional heat treatments such as annealing, hardening, carburizing, carbonitriding, vacuum heat treatments, nitriding, nitrocarburizing, normalizing, solution treat and age hardening, stress relieve, and many more.” Bluewater is similar to a few of the companies on this list in that it is owned by a venture capital firm.
#6 Solar Atmospheres
Solar Atmospheres Heat Treating Operations. The Solar Nation heat treating plants includes Souderton PA, Hermitage PA, Fontana CA, and Greenville SC, and have in total 357,000 square feet of plant space.

Their business largely relies on the Japanese automotive transplants.
#11 Dowa Thermotech
Globally Japan based Dowa Thermotech is one of the largest commercial heat treaters in the world so it is no surprise that it also ranks as one of the largest in North America. Their facilities in San Luis Potosi, Mexico and Bowling Green, Kentucky are both dedicated to servicing the Japanese automakers which means that they largely “fly under the radar” and don’t usually appear on lists of commercial heat treaters.

#47 Akron Steel Treating, Akron, Ohio
The history of Akron Steel Treating in Akron, Ohio makes for fascinating reading. In 1943, the U.S. army helped Prosper P.

Operating in the secrecy of soaped windows and late-night deliveries, with overflow work conducted in the family’s kitchen oven, Powell launched a successful company. When World War Two was over Prosper asked the US government when they wanted the furnaces back. 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.
