hard felt barrel
Product description:
The hard felt barrel is specially designed for powder metallurgy vacuum furnaces/pressure furnaces. It has excellent thermal shock and oxidation resistance. It can work stably in a high temperature vacuum environment for a long time, greatly extending the service life of the furnace body.
Product features:
- High relative mechanical strength
- Good density uniformity
- High purity, low ash
- Good processability
- Excellent thermal insulation performance
- High temperature oxidation and erosion resistance
