AWS A5.9 : ER309L
EN 14343 B : SS309L
JIS Z 3321 : Y309L
Characteristics:
It is the low carbon content designed to prevent intergranular corrosion.It is used to join similar 309L alloys or join 300 series stainless steels to carbon or low alloy steels.
Applications:
It is used for oil and gas refineries, include welding of AISI 309 in chemical and welding of dissimilar base metals of stainless and carbon steels.
Notes on Usage:
- For TIG process, use DC(-) current , Argon Shield and Tungsten Electrode.
