SUPERMIG 316LSi is a G 19 12 3 LSi/ER 316LSi type solid MAG welding wire, supplied precision layer wound, depositing a low C-19Cr12Ni2.5Mo weld metal. Suitable for use with Ar+2%O2 or Ar+0.5…5%CO2 mixed shielding gases.
Premium Stainless Steel Mig Wire 12.5kg (300mm) Spools
Available in Wire Diameter sizes: 0.8mm, 0.9mm, 1.0mm, 1.2mm
- For use on 316 parent material, can also be used on 304 304L and other 300 & 400 series stainless steels
- Molybdenum content increases resistance to corrosion pitting
- 300mm 12.5kg Spools
SUPERMIG 316LSi is used for welding of 316 and 316L grade stainless steels, in a wide range of applications including the fabrication of pipe and plate. The higher Si level results in a smooth weld bead shape and even appearance with excellent toe blending particularly in fillet welds. The weld metal has a high resistance to pitting and crevice corrosion by non-oxidizing acids. Used for applications with service temperatures <400°C.
Precision layer winding technologies ensure smooth, virtually trouble-free feeding.
