Products Description

Hydrogen annealing furnace is specially designed for sintering or annealing materials in hydrogen or inert gas environment. Its maximum temperature can reach 1600°C at inert atmosphere or air,reach 1450℃ at hydrogen environment. It uses advanced new thermal resistance alumina fiber as the furnacechamber material and reliable MoSi2 rod as heating elements. For materials that need to be sintered in an inert gas or reducing gas environment (such as fluorescent materials, titanium alloys, etc.), this electric furnace is a very good choice.

Feature of Hydrogen Atmosphere annealing Furnace

1. Multi-purpose atmosphere furnace filling (including hydrogen)

2. The maximum temperature can reach 1600℃

3. Hydrogen ignition + hydrogen detection + explosion-proof device,Ensure safe use

4. Available from 1L to 36L,or customized
