Peace be unto you.

The term "bluing" I think is a rather generic term - treating a surface to aquire a blue colouration. Oxidation/passivation treatment on steels using heat, chemical or electrochemical treatments. Also come across term with respect to applying blue laquers for highlighting scribe marks and checking fits and flatness.

What material is your pistons made from? and what is purpose/function of treatment?

Thanks dear for your comments.

Basically it is a process of colouring the pistols.
The colour is not blue, rather it is a black colour with bluish etch. It is so called Bluing due to Blue Black appearance of the pistols.

Hi Sadaqat

Ashamed0002 I think I need to wear my reading glasses - interpreted pistols as pistons Cool If we are talking firearms/guns, then I suggest searching "gun bluing"

https://en.wikipedia.org/wiki/Bluing_(steel)

One process (I know as chemical blacking) uses a boiling solution of potassium nitrate, sodium hydroxide, and water.
