Solar Atmospheres recently installed an all-metal hot-zone vacuum furnace at its facility in Souderton, Pa. This is the heat treater’s third all-metal hot-zone furnace installation for its climate-controlled room. The new furnace increases Solar’s capacity for processing sensitive materials such as PH stainless, nickel-chrome-based superalloys, titanium and ferritic and austenitic stainless steels. 

The unique placement of isolation valves, an all-metal molybdenum/stainless steel hot zone and a stainless steel chamber allows this furnace to attain the level of cleanliness mandated by the demanding aerospace and medical markets. The ability to achieve vacuum levels lower than 5 x 10-6 Torr produces clean, bright results without contamination. The furnace also incorporates Solar Manufacturing’s SolarVac Polaris HMI control system for complete process automation.
