Description
Sifmig 309LSI Stainless Steel MIG Wire – 0.8 mm x 15 Kg
The Sifmig 309LSI is a stainless steel MIG wire with elevated chromium and nickel content. It’s designed for joining materials with a similar composition as well as dissimilar stainless steels.
Key Features:
- High Chromium and Nickel Content: Enhances the wire’s welding properties and corrosion resistance.
- Versatile Applications: Suitable 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.
