Captive Heat Treater Makes Substantial Heat Treat Investments

Chain manufacturer and captive heat treater Allied Locke in Dixon, Illinois, USA has graced the pages of “The Monty Heat Treat News” several times in the past because of their substantial investments in their heat treat department. Another recent investment has been into their metallurgical lab headed up by Mr. Troy Greene, who is quite proud of what the company has achieved. So proud in fact that he sent us these pictures of his upgraded lab. Gord Montgomery of “The Monty Heat Treat News” will be visiting this facility in a few weeks and we look forward to giving you some first hand details about the company.

“FEBRUARY 20th 2023. In House Heat Treater Continues to Expand Heat Treat Department; Headquartered in Dixon, Illinois, USA Allied Locke is a manufacturer of chain and chain products. Founded in 1965 as Allied Chains the company has grown and prospered over the years and now has five divisions: Agricultural Chain, Precision Roller Chain, Industrial Chain, Sprockets, and Environmental Products. The primary manufacturing facility (Plant 1) in Dixon, IL covers nearly 675,000 square feet. Home – Allied-Locke Industries (

The firm has always considered heat treating to be a “core competency” and to that end they have continued to invest and expand their heat treat department, to the point that it is becoming one of the larger captive heat treaters in the US. Currently Allied has 6 batch IQ furnaces, each 36″ X 72″ X 36″, 3 Can Eng mesh belt furnace lines and related equipment including endothermic generators. As we speak a 3rd Can Eng mesh belt line is being installed and plans include one more batch IQ line.

At the same time the company has recently installed what was described to us as an “amazing, new” metallurgical lab and is working towards CQI-9. So often heat treating is an afterthought in manufacturing firms and is relegated to that dark dirty area at the back of the plant. It makes our day at “The Monty Heat Treat News” to see that some companies rightfully understand the importance of heat treating-Allied Locke is certainly one of these.”
