Description
|
OTF-1200X series high-pressure split tube furnaces can be chosen from two kinds of alloy tubes, e.g. Stainless steel 310S refractory alloy or Ni-based superalloy, which offer a solution of heating treatment under high positive pressure with/without inert gas support to process special compound material. The furnace can be heated up to the max. 900°C or 1100°C with the optional vessel. The operating positive pressure is from 105 to 800 psi according to different heating temperatures.
