HORDA 309L
ISO 14343 A/B:
W 23 12 L I1
AWS A5.9:
ER 309 L
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 309L 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 309L has good general corrosion resistance.
