OK Tigrod 308LSi GTAW
ER308LSi
Description
Bare, corrosion-resistant, chromium-nickel rods
for welding austenitic chromium-nickel alloys of
the18% Cr-8% Ni type.
OK Tigrod 308LSi has good general corrosion
resistance. The alloy has a low carbon content
which makes it particularly recommended when
there is a risk of intergranular corrosion. The higher
silicon content improves the welding properties
such as wetting. The alloy is widely used in
the chemical and food-processing industries, as
well as for pipes, tubes and boilers.
