Avesta GT 309L

Characteristics and typical fields of application

Avesta GT 309L is a high-alloy 23 Cr 13 Ni wire primarily intended for surfacing low-alloy steels and for dissimilar welding between mild steels and stainless steels, offering a ductile and crack resistant weldment. The chemical composition when surfacing is equivalent to that of ASTM 304 from the first run. One or two layers of 309L are usually combined with final layer of 308L, 316L or 347.

Base Materials

Primarily used when surfacing unalloyed or low-alloy steels and when joining non-molybdenum-
alloyed stainless and carbon steels.
