Manufacturing process
- Pre-clean steel parts in a hot alkaline soak cleaner and rinse thoroughly.
- Perform anodic etching in a chromic sulphuric bath for 1-2 minutes for proper adhesion.
- Transfer the parts to the plating bath for the hard chromium deposition process.
- Rinse the plated parts in a drag-out tank followed by water rinsing and hot water rinsing.
- Heat components of hardened steel to at least 200 degrees Celsius to eliminate hydrogen embrittlement.
