Need black finish for 304SS
I'm looking for a finishing process for 304 stainless steel which results in a high emissivity for thermal radiation cooling. The current plan is to electro polish so the surface is smooth for cleaning but this leaves a low emissivity surface. Something similar to anodizing for aluminum is what I have been thinking of. In addition, who can perform this work on a 180" x 85" D x 0.25" thick cylinder.
Note that the cleanability is important, no pits, cracks, etc..Dick Hartung
