Abel-black surface treatment is most suitable for elevated temperature equipment because of the emissivity improvement.

As Abel Black® has been black color, that is why it is said to be superior in function.
For example, Abel-black is understood to be more efficient in emissivity (in other word radiation which shows the coming out degree of the heat from the surface once absorbed) than stainless material.
Since it is superior in thermal conduction, providing the treatments to vacuum dry equipment and cooling apparatus, Abel Black® becomes useful as high functional material which displays heat absorption and thermal radiation.
