Muffle furnace for stainless steel
MAHLER continuous belt furnace for brazing and annealing high-alloy steels and various other alloys. Hydrogen or forming gas is typically used as the protective gas. The muffle furnace is available in various configurations:
Horizontal design (h)
Crested design (b)
MAHLER continuous belt furnaces with a recessed design are particularly suitable for materials requiring very good atmospheric quality.
Arched design:
- Width: up to 1,000 mm (or upon request)
- Pass-through height: up to 500 mm (or upon request)
- Heating zone length: up to 10,000 mm
- Operating temperature: 500 – 1150°C
- Atmosphere: N₂/H₂ mixed gas or dissociated ammonia
- Heating: electric or gas-fired
Advantages:
- Zoned gas supply for low protective gas consumption
- Suitable for processes with high requirements (e.g., brazing with nickel‑based brazing alloys)
- Heat‑resistant steel muffle for excellent dew point performance
- Very low protective gas consumption
- Extremely stable gas column
- Outstanding temperature uniformity


Horizontal design:
- Width: up to 1,300 mm (or upon request)
- Pass-through height: up to 150 mm (or upon request)
- Heating zone length: up to 10,000 mm
- Operating temperature: 500 – 1150°C
- Atmosphere: N₂/H₂ mixed gas or dissociated ammonia
- Heating: electric or gas-fired
Advantages:
- Zoned gas supply for low protective gas consumption
- Suitable for very long parts, e.g., tubes
- Heat‑resistant steel muffle for excellent dew point control
- Very low protective gas consumption
- Extremely stable gas column
- Outstanding temperature uniformity
