K chamber furnaces for additive manufacturing up to 1300 °C

The chamber furnace for heat treatment of 3D components

The chamber furnace for heat treatment of 3D components produced by additive manufacturing technology which ensures a process for correct metallurgical properties of metallic alloy.


Processed material type: stainless steel, nickel alloy and cobalt-chromium alloys

Furnace type
100x100 K 40/13
250x250 K 120/13
400x400 K 216/13
420x520 K 500/13
400x800 K 715/13


Steel components and nickel and cobalt-chromium alloys produced using the AM technology are processed in protective atmosphere at a temperature up to 1,100 °C. Up to 1,300 °C without a box with protective atmosphere intake.
The K furnaces are suitable for heat treatment of metals such as e.g. annealing, solution annealing, soft annealing, tempering, curing and internal stress relieving. It is possible to change a standard furnace into the variant with protective atmosphere intake by using a protective box.
