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