The gases commonly used in furnace atmospheres for heat treatment processes include hydrogen, nitrogen, oxygen, helium, argon, carbon monoxide, carbon dioxide, ammonia, propane, methane, and butane.
One commonly used atmosphere is the endothermic atmosphere, which is produced by cracking methane into nitrogen, hydrogen, and carbon monoxide in a retort. The typical composition of this gas is 40% H2, 20% CO or CO2, and 40% N2. This atmosphere helps protect the component parts being heat-treated by reducing the risk of oxidation.
Nitrogen or argon-controlled atmospheres are also commonly used in furnaces for heat treatment. These inert gases are introduced into the furnace to reduce the risk of oxidation and as a safety measure to purge flammables, oxygen, and water from the furnace. The amount of gas flow required varies based on the furnace volume.
Another gas used in furnace atmospheres is hydrogen. It is used in processes that require a hydrogen atmosphere, as it can provide a reducing environment and prevent oxidation.
It is important to note that the choice of gases used in furnace atmospheres depends on the specific heat treatment process and the desired outcome. Different gases can produce different effects on the material being treated, and the selection of gases should be based on the desired results and the material's sensitivity to oxidation or other reactions.
