SECO/WARWICK will deliver a retort furnace with vacuum purging for oxidation to a tool manufacturer. The furnace for the oxidation process operates under a nitrogen and hydrogen mix and then under steam. It will be adjusted to the individual needs of the tool manufacturer, providing the appropriate final hardness and color of the workpieces. The retort furnace, which will also enable tempering after vacuum purging, will be designed with a customized heating chamber so that it is compatible with the tooling used in the production process and so that the process itself is safe and repeatable. 

The behavior of high-temperature alloy constructions used in oxidizing environments is important for processes like PM sintering and thermal processing of advanced steels.

The protective gas chamber furnace includes a gas-tight muffle for heat-treatment processes under protective gas atmosphere up to 1050°C (1922°F).

The effect of hydrogen on aluminum alloys can manifest itself in a phenomenon known as high-temperature oxidation (HTO), also known as high-temperature deterioration (HTD).

RA 602 CA® – also known as 602 CA® and NiCroFer 6025, which are trademarks of VDM – is a relatively new heat-resistant alloy with excellent creep strength at very high temperatures and oxidation resistance up to 2250°F (1232°C).

The first factor in choosing a heat-resistant alloy for a particular application is its temperature limit.
