OK Tigrod 309LSi 2,0
[165120R150] |
OK Tigrod 309LSi GTAW
ER309LSi
Description
Bare, corrosion-resistant, chromium-nickel welding
rod for welding steels with similar composition,
wrought and cast steels of the 23% Cr-12%
Ni types. The alloy is also used for welding buffer
layers on CMn steels and for welding dissimilar
joints. When using the wire for buffer layers and
dissimilar joints, it is necessary to control the
dilution of the weld.
OK Tigrod 309LSi has good general corrosion
resistance. The higher silicon content improves
the welding properties such as wetting.
