The Monty’s 50 Largest North American Commercial Heat Treats 2021 – #35 Voestalpine AG

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 This year readers will see we became much more ambitious and expanded the list to the 50 largest. In our 35th spot we have Voestalpine AG.

Voestalpine AG is an Austrian steel-based technology and capital goods group based in Linz, Austria. With over 30 locations around the world offering heat treating the company would rank as one of the larger commercial heat treaters in the world. While their heat treating operations in North America are relatively modest compared with their global footprint they do operate two very impressive facilities in North America, one in Canada and one in Mexico. We have no doubt but they deserve to be on this list. This photo shows their Canadian facility.
