Once the debinding step is completed, the components are laid into a sintering furnace where they are heated until they reach a temperature which is lower than the melting temperature of the metal powder's main constituent. During this process, the powder mass bonds and this allows to achieve a near full density component.

Heat Treatment Furnace Atmospheres: Inert Gas and Hydrogen

While nitrogen is non-reactive with most steels, it may react with others above certain temperatures. In general, argon and helium are more inert than hydrogen. A pure nitrogen atmosphere provides blanketing of the part being heat treated and can be used to purge the existing atmosphere or be used as a carrier gas for carbon-controlled atmospheres.
