Seabrook Stainless Steel Fasteners & Fixings
Some information about the CB10 coating used to finish our black stainless steel range.
Our black stainless steel coating, known as CB10 or Oxi Black, is a super strong layer bonded to the metal's surface. We use this coating for most of our black stainless steel fasteners including our A4 316 grade stainless steel marine fasteners, as the surface bonding is excellent whilst giving a deep black colour.
CB10 is highly scratch resistant. In fact, you would need to cut in to the metal surface to remove the coating. Stainless steel is almost twice as hard as mild steel, so this is the perfect coating for longevity.
CB10 is also highly corrosion resistant, as it does not effect the corrosion resistance properties of the stainless steel. We have tested the CB10 black A2-70 stainless steel bolts by leaving them outside for over 3 years in the north of England. Through 3 winters, including the wettest December on record, there is still no sign of corrosion.
