ER316LSi Stainless Steel GMAW (MIG) welding alloy


ER316LSi Stainless steel GMAW (MIG) welding wire is primarily used to weld low carbon molybdenum-beaing austenitic alloys. The lower carbon content of .03% max. is used to avoid carbide precipitation. The additional silicon content increases the wetting action and yields a smooth bead.


  • Stainless steel 316LSi wire welds type 316 and similar alloys
  • Successfully used for high temperature applications
  • 88,000 psi tensile strength (as welded)
  • 59,000 psi yield strength (as welded)
  • 40% elongation; 60% reduction of area (as welded)
  • 89 HRB Rockwell B hardness (as welded)
  • 180 HRB Brinell hardness (as welded)
  • 45 ft./lb. @ room temperature Charpy V (as welded)
  • Conforms to ANSI/AWS A5.9, ASME SFA 5.9 CLASS ER 316LSi
