OK Tigrod 308LSi


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.
