Pickling bath

Pickling bath are used for pickling heat treated and welded stainless steel structures. At pickling the annealing scales and/or welding oxides are removed from the surface of the stainless steel. After pickling and ample rinsing with water (high pressure) the corrosion resistance is restored in the welded area.

TACAB NOXfree pickling bath

Use only together with austenitic and duplex stainless steel grades. Developed for stainless and acid resistant steel. The pickling baths used today are almost always hazardous to health and emit dangerous gases and the use demands very strict directives for ventilation, protective equipment etc. TACAB noxfree pickling bath is patented, environmentally suited pickling bath that drastically reduces the hazardous at use. No toxic and  environmentally harmful gases are given of during pickling process. The useful life of the noxfree pickling bath is much longer than for a conventional nitric acid - hydrofluoric acid bath.

TACAB noxfree pickling bath is sold in the following sizes of packages: 25, 200 and 1000 litres.
For larger volumes ask for quotation.


TACAB pickling bath concentrated

Traditional pickling bath (nitric/hydrofluoric acid) . Chooses work area for the pickling bath and then mix theproduct  with water ​to the desired strength. The bath can be mixed to process stainless/acid resistant steel, duplex, or to pickle very high alloyed stainless steel grades (eg, Super duplex).

TACAB pickling bath concentrated is a traditional pickling bath based on hydrofluoric acid and nitric acid. TACAB pickling bath concentrated is sold in the following sizes of packages: 25, 200 and 1000 litres.
For larger volumes ask for quotation.

How to prepare TACAB pickling bath concentrated:

Stainless and acid resistant steel grades.  Mix ratio 1:2 (1 part concentrated pickling bath + 2 parts of water).

Higher alloyed steel grades (example: duplex).  Mix ratio 1:1 (1 part concentrated pickling bath + 1 part of water).

Very high alloyed steel grades (example: super duplex). Mix ratio 1:0.5 (1 part concentrated pickling bath + 0.5 parts of water).

Use only fresh water (drinking waster quality, preferably below 50 ppm).


Maintenance product for TACAB NOXfree pickling bath. Adjust the level of the NOX-free pickling bath by adding 1 part TACAB NFM 1000 and one part water (drinking water quality with chloride content <50 ppm).
