A continuous, solid ,corrosion-resistant, chromium-nickel wire for welding steels with a similar composition, wrought and cast steels of the 23%Cr-12%Ni types. The wire is also used for welding buffer layers on CMn steels and welding dissimilar joints. When using the wire for buffer layers and dissimilar joints, it is necessary to control the dilution of the weld from parent metal side. HORDA 309LSi has good general corrosion resistance. The higher silicon content improves the welding properties such as wetting.
