THE BLACKFAST PROCESS

The Blackfast Process is a Surface Conversion process.

As with the Iron and Steel Blacking process, the stainless-steel blacking process operates with a 7- stage dipping process.

The process equipment required is a simple arrangement of polythene tanks and ideally running water rinses.

Processing entails degreasing, pickling, blacking and lastly an immersion in a dewatering oil, all with intermediate water rinses. For the stage of Pickling, it is recommended that you have extraction over this tank as a strong acid pickle is used.
