Detroit Flame Hardening Co. was founded in 1941 by Marvin R. Scott, a metallurgical engineer within a
major gas corporation. Marvin had a vision for a new, groundbreaking innovation in the flame-hardening
process and this vision led to the establishment of the Detroit Flame Hardening Company, propelling this technique into industrial prominence.

Detroit Flame has become a globally recognized entity. With two additional locations in
Cincinnati and Cleveland, we have both expanded our reach and expanded the range of our services. For
over 80 years, we have refined and perfected our processes, delivering only the best flame-hardening service to diverse industries nationwide.
