OK Tigrod 318Si

Bare corrosion resisting stabilized chroumium-nickel-molybdenium wire for welding of Cr-Ni-Mo and Cr-Ni stabilized or non-stabilized steels. OK Tigrod 318Si has a good general corrosion resistance. The alloy is stabilized with niobium to improve the resistance against intergranular corrosion of the weld metal. The higher silicon content improves the welding properties, such as wetting. Due to stabilization of niobium this alloy is recommended for service temperatures up to 400°C.
