Our History

Mervin M. Sirrine started Flame Treating Systems, Inc. near Pittsburgh, PA in 1973 after working for Dow Chemical (developers of Mapp gas), Airco and Pennsylvania Flame Hardening.   Merv believed he could solve just about any hardening problem using a controlled flame hardening system for considerably less cost than an induction system.   Mark M. Sirrine (right) has continued this philosophy since taking over as president and owner of Flame Treating Systems from his father in 1995.

With over 40 years of experience, we at Flame Treating Systems Inc. have become experts on the control of the flame system.  With our personal service we can analyze your hardening problems and recommend a solution that works within your budget: either a turnkey system to put on your shop floor, or using our own equipment to flame harden your parts for you.
