Our History
Mervin M. Sirrine
Mervin M. Sirrine founded Flame Treating Systems near Pittsburgh, PA, in 1973, after working for Dow Chemical (the developers of Mapp gas), Airco, and Pennsylvania Flame Hardening. Merv believed that he could solve almost any hardening problem using a controlled flame hardening system at a fraction of the cost of an induction system. Unfortunately, we lost Mervin on June 20, 2018. He left an incredible legacy, and he will be dearly missed. *Mervin Sirrine: October 13, 1930 – June 20, 2018.
