Description
Sifmig 309LSI Stainless Steel MIG Wire – 1 mm x 15 Kg
The Sifmig 309LSI is a stainless steel MIG wire enriched with higher levels of chromium and nickel. This composition makes it suitable for welding materials of similar composition as well as dissimilar stainless steels.
Key Features:
- Elevated Chromium and Nickel Content: This enhances the wire’s welding properties and offers superior corrosion resistance.
- Versatility: Designed for joining both similar and dissimilar stainless steel materials.
Material to be Welded
Typical applications include joining high-strength steels, un- and low alloyed heat treatable steels, stainless, ferritic chromium and austenitic chrome-nickel steels, austenitic manganese steels. SIFSTEEL 309LSi is suitable for joining clad steels. The FN content (FN~16) ensures good cracking resistance.
Base materials to be welded: High strength, unalloyed and alloyed heat treatable steels; stainless, ferritic chromium and austenitic CrNi steels; austenitic manganese steels. Chemically resistant weld claddings ranging from ferritic-pearlitic steels to fine grain steels, incl. high temperature fine grain steels. Dissimilar joining.
