There can be nothing more devastating to a heat treater than a fire-unfortunately it is a not uncommon occurrence. These photos which were taken just yesterday show Elk County Heat Treaters in St. Marys, PA, USA. It is too soon to know what caused the fire however luckily there were no injuries. Elk county is a well established, medium size commercial heat treater. It is located in the city of St. Marys which is the powdered metal capital of the world and because of this the area has a very substantial amount of heat treating in relationship to the size of the area.
