OK Tigrod 308L
OK Tigrod 308L is a bare, corrosion-resistant, chromium-nickel TIG rod. OK Tigrod 308L has a good general corrosion resistance. The alloy has a low carbon content which makes this alloy particularly recommended where there is a risk of intergranular corrosion.
Features
OK Tigrod 308L is widely used in the chemical and food processing industries as well as for pipes, tubes and boilers. Suitable for the joining of stainless steels of 18% Cr - 8% Ni-type with low carbon content and Nb-stabilized steels of the same type if the service temperature does not exceed 662°F (350ºC). Can also be used for welding of Cr steels except in sulphur-rich environments.
