Pickling paste Formula 1
Fast and effective pickling paste for
welded stainless steel constructions
Sandvik pickling paste Formula 1 is an effective pickling paste used
for cleaning and passivating welding joints and the heat affected
zone (HAZ) for welded stainless steel constructions.
The pickling paste removes the naturally occurring oxide layer
and the chromium depleted layer under the oxide. The result is
a perfect weld with the required corrosion resistance.
Excellent adhesion and economical to use
Sandvik pickling paste Forumla 1 is rapid and economical to use,
as only a thin film of the pickling paste is required for a perfect
result. The pickling paste has excellent adhesion and can be
applied on vertical surfaces and ceilings without any risk of
running or drying. This is due to the gel-like (thixotropic),
homogenous consistency. The paste’s consistency also makes
it easy to apply without splashing, particularly important because
of its aggressiveness.

bead or a surface of approximately
6 m2 (64.58 ft2 )
Instructions for use
The pickling paste is applied with a brush.
The pickling times, which are dependent on temperature,
type of steel and welding method vary between
30–240 minutes at room temperature.
Working temperature +5 to +40ºC (+41 to +104ºF).
Rinsing is done with water (high pressure).
The pickling should as far as possible be done indoors in well
