STAVINOX 308Si / 308LSi

Main Features and Benefits

STAVINOX 308Si / 308LSi performs consistently across a broad range of stainless steel welding applications.

• Extra low-carbon weld metal Lowers the risk of intergranular corrosion in welded joints.
• Smooth and stable weld bead The silicon content improves bead appearance and wetting while welding.
• Good corrosion resistance The weld metal withstands intergranular attack from many liquid media.
• Strong mechanical properties Strength and elongation remain good after welding.
• Wide material compatibility Suited to welding common 18 chromium and 8 nickel stainless steels.
• Reliable arc stability Gives a steady arc in both MIG and TIG welding processes.

As a result, ER308LSi works well for production welding as well as general fabrication.

The table that follows sets out the key mechanical properties and welding conditions for STAVINOX 308Si / 308LSi.

Properties

308Si / 308LSi welding consumables are commonly chosen for stainless steel fabrication where corrosion resistance, weld quality and appearance are priorities.

• Austenitic Stainless Steel Weld Metal – Suits 304 and 304L stainless steels and gives stable, dependable welds.
• Good Corrosion Resistance – Works well in mild to moderate corrosive environments, so it fits general industrial and fabrication use.
• Low Carbon Content (308LSi) – Reduces the risk of intergranular corrosion after welding, particularly in joints exposed to moisture.
• Enhanced Silicon Content – Improves weld pool fluidity for a smooth bead shape and a clean weld appearance.
• Excellent Weld Appearance – Gives uniform, bright beads with good wetting, so less post-weld finishing is needed.
• Good Mechanical Strength – Offers adequate tensile strength and ductility to cope with service stresses and thermal expansion.
• Stable Arc and Easy Weldability – Feeds smoothly, produces low spatter and performs consistently in both MIG and TIG welding.

The ER308LSi welding wire performs reliably in shop fabrication and in site welding alike.
