Cold metal blackening offers corrosion resistance without high-temperature hazards
- December 11, 2013
- Product Release
- Finishing
Presto Black® cold blackening from Birchwood Technologies produces a uniform depth of blackness and corrosion resistance that is a suitable finish for oil and gas drilling components.
The room-temperature process provides high corrosion resistance tested for up to 1,200 hrs. of humidity exposure. With a uniform 0.000030-in. thickness, the porous crystalline structure of the finish makes it an absorbent base for a rust preventive topcoat for extra corrosion protection without chipping or peeling.
The process is recommended for blackening parts made of cold- and hot-rolled steels, alloy steels, tool steels, cast iron, forged steels, and powdered metal. The 15-min. process is suitable for any quantity of large or small parts, from prototypes and short-run parts to long runs, including JIT finishing programs.
