Pickling paste for stainless and acid-resisting stainless steels

Stainclean pickling paste is used as the Step 2
chemical in steel welding process after Stainflux
application on root side prior to welding.
Stainclean cleanses and passivates welded joints
and the heat affected zone (HAZ). Used on welded
stainless steels it leaves a clean professional
finished weld area. After pickling and ample rinsing
with fresh water with low chlorine content (preferably
<20 ppm), the corrosion resistance of weld area is
restored.
Compatible with all 200,300 and 400-series stainless
steels, precipitation hardened and maraging alloys
(excluding free machining alloys such as 303,
304Cu, 316L, 430F, 416, 430F, 420 & 420F).

Highlights

  • Restores the corrosion resistance (forms the passive chromium oxide layer)
  • Gives a bright welding joint and HAZ, clean from oxides and discolorations
  • Efficient and economical. A thin layer 0.5 – 1.0 mm is sufficient for perfect results
  • Instructions of use:
    1. Clean the surface
    2. Apply on the required area
    3. Wait 5 minutes
    4. Rinse thoroughly with demineralized water or water
      with chlorine content <20 ppm
