ISO 14343 A/B:
S 23 12 L Si
AWS A5.9:
ER 309LSi
ГОСТ 2246-70:
Св-07Х25Н13
A continuous, solid ,corrosion-resistant, chromium-nickel wire for SAW 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. HORDA 309LSi has good general corrosion resistance. It can be used in combination with fluxes AB, AF, FB types (EN ISO 14174) class 2.
