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.
