Thermocouple protection tube for high temperature salt bath furnace , the lifespan will be 1 month when it is used to the liquid of 1280℃.
Its main material composition Mo and Al2O3.
Thermocouple protection tube can resist the corrosion of steel liquid , the life span will be 24 hours when it is used to 1450 and 1560 steel liquid.
Properties
(1).Good tenacity
(2).High temperature resistance
(3).High thermal conductivity
(4).Corrosion resistance
(5).Good thermal stability
(6).Wear resisrance
1. High temperature resistance
The strength keeps stable up to 800℃ and it can even momentarily used at 1500℃.
2. Wear resistance
Due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix, it has exceptional wear and galling resistance.
3. Corrosion resistance
This exellent and lovely property allows this kind of material parts to be used in oil&gas, slurry, acid liquid and any other mediums.
