Most atmospheres currently used for sintering parts in continuous belt furnaces contain nitrogen as a primary constituent of the atmosphere. It is important to understand the differences in nitrogen-bearing atmospheres from a cost and qualitative benefits standpoint.
**********
Nitrogen gas is used primarily as a carrier gas that protects powder-metal components from oxidation and excessive decarburization during the sintering process. Most atmospheres currently used in sintering parts in continuous belt furnaces contain nitrogen as a primary constituent of the atmosphere, which offers stability, safety and reliability in the process. It is important to ...
