Among our other services including electroless nickel plating; we also offer the option of metal pickling.
Pickling can be used to effectively remove impurities from a metal surface such as stains, rust or scale. This type of metal surface treatment uses strong acids to remove impurities from the surface of the metal and is commonly used to clean or descale steel.
We have recently been involved with a project pickling stainless steel for the Aerospace group Meggitt. The components, which were to be used in a project in offshore Brazil, were pickled using hydrofluoric and nitric acid.
These types of acid are effective in removing discoloured scale from stainless steel.
Many processes that occur at a high temperature can leave a discolouring oxide residue or scale on the surface of the metal. Pickling the component removes the scale from the surface of the metal, leaving it looking much cleaner and brighter.
Acids are difficult to handle because they are so corrosive. Therefore, pickling is a process that requires the upmost care and safety. Luckily, we have the experience and expertise to carry out this process safely.
