Stainless Steel Passivation

Stainless steel passivation is performed to form a chemically inactive surface when exposed to air or other oxygen environments without changing the outward appearance of the component. The process is predominantly carried out where there is the potential for iron particles to be present on the surface of components as contamination after machining which if not removed would corrode and therefore weaken the part.

Plating Capabilities

  • Nitric dichromate passivation
  • Citric acid passivation
  • Humidity Testing available
  • Precision masking available for selective passivation

Example Specifications

  • Defence Standards (DEF-STAN)
  • Aerospace Material Specification (AMS)
  • British Standard (BSEN)

Typical Applications Of Stainless Steel Passivation

  • Aerospace, used in passivation of steel parts likely to be contaminated with iron particles
  • Medical, used in passivation of equipment
The turnaround times are good and the back office support is good too.
They are consistent, reliable and I have a good working relationship with them
They are the most cost effective and have a quality finish
They are based in a prime location and they have good technical capabilities.
I recently dealt with your Paint division who have renovated the railings from my house. I am extremely pleased with the finish considering what they initially had to work with. Noel Pascoe - Retail Customer
