A family owned company over its entire existence, Chicago Flame Hardening holds a unique place in the metal-treating industry. The founders of this company pioneered the flame-hardening process for a major manufacturer of industrial gases. Recognizing a broader use for surface-hardened metals, they pursued the marketing of their new technique to various industries that still make up their customer list today.

Over the years, this format has been continually refined to incorporate its current high-tech processing and controls. We continue to set the bar higher for ourselves and our clients, whose industrial accounts represent steel, construction, mining, paper, railroad, crane and gear manufacturers, as well as machine tool, tool and die and agriculture.

Chicago Flame Hardening continues to make advances in surface hardening techniques. Our experienced technical staff can readily assist you with any application and offer recommendations. The economic savings and service you will find at Chicago Flame Hardening make us the preferred solution to wear problems.
