ER308L is a low-carbon stainless steel welding wire primarily used for welding 304 and 304L stainless steels. It offers excellent weldability, good corrosion resistance, and strong mechanical properties, making it one of the most widely used filler wires for austenitic stainless steel welding applications.
SS ER308L wires are solid austenitic stainless steel filler wires used in TIG (GTAW) and MIG (GMAW) welding processes. The designation:
The low carbon content reduces the risk of carbide precipitation during welding, thereby preventing intergranular corrosion in the heat-affected zone.
ER308L wires are widely used for welding stainless steels such as 304, 304L, 321, and similar grades.
Key Features of SS ER308L Wires
These properties make ER308L a preferred filler material for stainless steel fabrication.
| Element | Composition (%) |

Role of Key Elements
The balanced composition ensures a stable weld deposit with reliable mechanical properties.
Typical mechanical properties of deposited weld metal:
The weld metal exhibits good ductility and crack resistance, ensuring long-term structural integrity.
These properties ensure stable performance under thermal cycling and moderate temperature conditions.
ER308L weld deposits provide good resistance to:
Due to its low carbon content, ER308L minimizes the risk of sensitization after welding. However, for highly corrosive chloride environments, ER316L may be a better option.
SS ER308L wires are widely used in:
Suitable Base Metals:
It is commonly used for fabrication where corrosion resistance and structural strength are required.
Preheating is generally not required. Post-weld heat treatment is typically unnecessary for most applications.
