HORDA 309LSi
ISO 14343 A/B:
W 23 12 LSi I1
AWS A5.9:
ER 309 LSi
ГОСТ 2246-70:
GTAW corrosion-resistant, chromium-nickel rod for welding steels with a similar composition, wrought and cast steels of the 23%Cr-12%Ni types. HORDA 309LSi is also used for 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. HORDA 309LSi has good general corrosion resistance. The higher silicon content improves the welding properties such as wetting.
