HYW ER308LSi High-Silicon Stainless Steel MIG Welding Wire

HYW ER308LSi High-Silicon Stainless Steel MIG Welding Wire is a low-carbon (L), high-silicon (Si) austenitic stainless MIG wire (19% Cr / 9% Ni) for welding AISI 301, 302, 304 and 304L stainless steels. The elevated silicon content improves puddle wetting and fluidity for faster, flatter beads and reduced spatter, making it ideal for high-deposition production welding, while the low carbon level guards against intergranular corrosion. Supplied on large production spools. Key Features › Elevated silicon (LSi) chemistry for superior wetting, fluid puddle and flatter beads › Low-carbon (L) base minimizes carbide precipitation and intergranular corrosion › Reduced spatter and easy slag / oxide cleanup for bright, clean welds › Large 8 lb & 25 lb production spools for high-deposition, high-volume welding Ideal Applications › High-volume production welding of 304 / 304L and 308 / 308L stainless › Food, beverage, dairy and brewing equipment › Tanks, railings, sinks and architectural stainless fabrication › Automated / robotic and semi-automatic GMAW where feedability matters Technical Specifications AWS Classification AWS A5.9 / A5.9M ER308LSi Wire Type Solid low-carbon, high-silicon austenitic stainless steel (19% Cr / 9% Ni) Process MIG / MAG (GMAW) Polarity DC+ (DCEP / reverse polarity) Shielding Gas 98% Ar / 2% O₂, or tri-mix (90% He / 7.5% Ar / 2.5% CO₂) for short-circuit Packaging 8 lb & 25 lb plastic production spools Typical Chemical Composition Typical filler-wire analysis (wt %). Single values are maximums; iron is the balance. Element Typical Wire (wt %) Carbon (C) 0.03 max Chromium (Cr) 19.5 – 22.0 (typ. 20.5) Nickel (Ni) 9.0 – 11.0 (typ. 10.0) Manganese (Mn) 1.0 – 2.5 (typ. 1.8) Silicon (Si) 0.65 – 1.00 (typ. 0.85) Phosphorus (P) 0.03 max Sulfur (S) 0.03 max Iron (Fe) Balance Available Sizes & Recommended Amperage Diameter Recommended Amperage .035″ (0.9 mm) 50 – 180 A .045″ (1.2 mm) 75 – 350 A Recommended amperage ranges are general guidelines; optimal settings vary with base-metal thickness, joint design, shielding gas, and welding position. Store wire in a dry location to prevent oxidation and ensure smooth feeding. ⚠ WARNING: This product and the fumes and gases produced when welding it can expose you to chemicals including nickel and hexavalent chromium compounds, which are known to the State of California to cause cancer, and manganese, which is known to cause birth defects or other reproductive harm.
