As experts in the various processes of metal finishing, and often the company of choice for several aerospace companies, NiTEC recently took on a project pickling steel for world renowned Aerospace group Meggitt.
Meggitt PLC – Engineering for Extreme Environments
Meggitt PLC is a global engineering group specialising in extreme environment components and sub-systems for aerospace, defence and energy markets.They are a FTSE 100 supplier of aircraft parts, and they supply flight displays and wheels to both Boeing and Airbus.
Why Pickle Stainless Steel?
The process of pickling stainless steel is a metal surface treatment that is used to remove any impurities from the surface of the metal. This could be stains, inorganic contaminants, and rust or scale. Acid is commonly used to remove these surface impurities.
The Safe Handling of Hydrofluoric Acid
Staff at NiTEC used hydrofluoric and nitric acid to remove the discoloured scale from the stainless steel, and as you can see from the pictures, the process makes a huge difference to the surface of the steel.
Hydrofluoric acid is a really effective acid for pickling; although it is typically more expensive than other acids, the process of pickling is much quicker and it effectively minimises the base metal loss.
We had the exciting task of pickling stainless steel for a project located in offshore Brazil and were lucky enough to be chosen as partners in the project because of our expertise in the safe handling of hydofluoric acid, which is an integral part in the process we carried out for Meggitt.
