GSM beizpaste

Why is it necessary to stain stainless steel material?

The pickling process is the process of restoring the corrosion resistance of stainless steel materials after operations such as welding, heating or bending.

A common method of staining stainless steel surfaces is surface treatment using a strong solution of nitric acid and hydrofluoric acid.

Beizpasta is used to clean the staining blackness created during welding.

In order to achieve better results when staining, it is necessary that the surface to be processed be cleaned of grease and other impurities.

Bwhile the paste is in a gel state, it is applied with a brush (which is resistant to acids) to smaller surfaces that need to be cleaned. Before use, it is necessary to shake the container in which the beizpasta is located.

Before applying the paste, it is necessary to mechanically remove the slag created during welding.>

After the paste is applied to the surface, it is necessary to wait 30 to 90 minutes for the chemical reaction to finish. At the end of the chemical reaction, it is necessary to wash the surface with water.
