Description
309LSi stainless steel GMAW (MIG) welding alloy has similar usage as 309L, but the 0.65-1.00% silicon content improves wash and wetting behavior in the gas shielded welding processes. Conforms to AWS A5.9.
Features
- Stainless steel 309LSi MIG welding wire welds 304 and similar base metals in wrought or cast form where severe corrosion conditions may exist
- Sometimes welds dissimilar steels
- Higher 0.65-1.00% silicon content improves the wetting and washing behavior of the weld metal
- 87,000 psi tensile strength (as welded)
- 58,000 psi yield strength (as welded)
- 48% elongation; 60% reduction of area (as welded)
- 85 HRB Rockwell B hardness (as welded)
- 160 HB Brinell hardness (as welded)
- 95 ft./lb. @ room temperature Charpy V (as welded)
- Conforms to ANSI/AWS A5.9 & ASME SFA 5.9 ER 309LSi
