Titanium parts manufactured by AM technology, which are processed in a protective atmosphere at temperatures up to 800 °C. AM nickel alloys processed to relieve stress at 890 °C.
PKRC furnaces are equipped with a hot-wall retort, protective atmosphere inlet and vacuum pump. They are suitable for heat treatment of metals and due to the circulation of the inner atmosphere they are characterized by excellent temperature distribution.
