Company Elnik has extensive experience manufacturing specialized furnaces. One of the largest batch furnaces Elnik ever created, pictured to the right, was used for annealing and stress relieving of titanium structural parts. The furnace can be used either under high vacuum or low partial pressure of flowing argon, offering flexibility for a wide variety of annealing process for specialty alloys. Its curved roof and bottom heating elements provide temperature uniformities. The inside of the chamber is stainless steel with a mild steel outer shell and includes the necessary water cooling. The hot zone incorporates several layers of stainless steel heat shields with molybdenum heating elements, using a six-zone temperature control top and bottom for each section and door.
