Product Description
ER309 and ER309L stainless steel welding wires have a wide range of applications in the field of stainless steel welding. Their main difference lies in the carbon content, which leads to differences in their resistance to intergranular corrosion. When selecting welding wire, it should be selected according to specific welding requirements and material properties. At the same time, during the welding process, the welding specifications should be strictly followed to ensure the welding quality.

Applications
ER309 stainless steel welding wire
Main uses:
Mainly used for welding the same type of stainless steel, as well as stainless steel lining, dissimilar steels (such as the connection between mild steel and chrome-molybdenum steel), high chromium steel, high manganese steel, etc.
The weld metal has excellent mechanical properties, crack resistance and oxidation resistance, and also excellent heat and corrosion resistance.
ER309L stainless steel welding wire
Main uses:
Also suitable for welding dissimilar metals, with excellent heat and corrosion resistance.
Particularly suitable for welding low-carbon stainless steel and low-carbon Clad steel, as well as welding SUS309S, heat-resistant steel 13Cr, 18Cr steel or dissimilar metals.
