Aerospace special-process providers seeking Nadcap accreditation agree that the process has elevated the level of compliance from procedural accuracy, training, documentation, equipment functionality and process control.
In many locations throughout North America, nitrogen oxide (NOx) emissions of gas-heated furnaces are limited by law or code. This is typically the case in urban areas or in places where special topographical characteristics intensify the negative local and regional effects of NOx emissions.
Since the development of commercial electric heating elements at the beginning of the 20th century, oxidation and corrosion resistance have been primary goals in the creation of new high-temperature resistance and construction alloys and ceramic materials.
Conserving energy and the CO2 reduction that accompanies it is a good thing for your company’s bottom line. In our energy-intensive industry, we are always on the lookout for the next thing to help us save.
Perhaps a half-dozen times over the course of The Doctor’s career have vacuum furnace users reported the presence of a white layer on the surface and near-surface of steel and stainless steel component parts after vacuum hardening and/or carburizing followed by vacuum oil quenching.
The September 2017 issue of Industrial Heating features our cover story on vacuum diffusion bonding for joining titanium alloys, along with best welding practices for heat-resistant alloys, and much more.
