ER309L

Characteristics and typical fields of application

TIG rod of W 23 12 L / ER309L type for welding dissimilar joints. Well-suited for depositing intermediate layers when welding of cladded
materials. Designed for very good welding and wetting characteristics as well as good safety after dilution when welding dissimilar joints.
Due to the high ferrite content, 16 FN, the weld metal is less susceptible to hot cracking. Suitable for service temperatures between –80ºC
and 300ºC.

Base materials

Primarily used for surfacing (buffer layer) unalloyed or low-alloyed steels and when joining non-molybdenum-alloyed stainless and carbon
steels.
