Why choose ABRAFIL 308LSi?

Perfect for 304/304L stainless steel (and similar)

  • Composition optimized for austenitic stainless steels with 18% chromium and 8% nickel.

  • The low carbon content (“L”) reduces the risk of intergranular corrosion after welding (no precipitation of chromium carbides).

2. Silicon-enriched = better welding properties

  • Si (~0.85 to 1.2%) improves :

    • The fluidity of the melt

    • Cord appearance: smoother, brighter and more attractive

    • Wettability: better edge fusion

    • Bow stability: fewer splashes, smoother bows

  • Ideal for visible welds, manual or automated work.

3. Excellent corrosion resistance

  • Excellent resistance to damp, atmospheric and food environments, etc.

  • For use in food processing, pharmaceuticals, architecture, etc.
