OK Tigrod 312
Bare, corrosion-resistant, chromium-nickel welding rods for welding materials of the 29% Cr, 9% Ni types.
OK Tigrod 312 has good oxidation resistance at high temperatures due to its high content of Cr. The alloy is widely used for joining dissimilar steels, especially if one of the components is fully austenitc, and for steels that are difficult to weld, i.e. machine components, tools and austenitic-manganese steels.
