About ER 309Lsi

ER 309LSi is a low-carbon, high-silicon stainless steel filler metal (wire/rod) known for welding dissimilar metals (like stainless to carbon steel) and similar stainless steels, offering excellent wetting for smooth beads, good corrosion resistance, and good high-temperature strength, with the 'Si' (silicon) improving weldability and appearance compared to standard 309L.

Key Characteristics:

Material: Austenitic stainless steel.
Low Carbon ('L'): Reduces carbide precipitation, increasing resistance to intergranular corrosion.
High Silicon ('Si'): Improves weld pool fluidity, wetting action, and bead appearance, making it easier to weld.
Excellent for Dissimilar Metals: Ideal for joining stainless steel to carbon steel or mild steel.
Good for Clad Steels: Used for overlaying or joining clad steels.
High Temperature Performance: Offers good heat and corrosion resistance up to around 300C (572F).
Weldability: Smooth, fluid weld beads, good for GMAW (MIG) and GTAW (TIG).

Common Applications:

Food service and beverage tanks.
Joining 18% Cr / 8% Ni stainless steels.
Buffering/buttering stainless steel surfaces.
Welding 3Cr12 steels.

In essence, ER 309LSi combines the benefits of low carbon and added silicon for superior performance in challenging stainless steel and dissimilar metal welding.
