TIG Rod ER308LSi Stainless Steel, 1.6mm Diameter, 1M Length

Brief Overview

The ER308LSi is an ultra-low carbon austenitic stainless steel TIG welding rod engineered for all-position applications across petrochemical, pressure vessel, food machinery, and medical equipment industries. The silicon addition ensures excellent molten pool flow, producing visually superior beads with minimal spatter and smooth feeding characteristics. Ideal for welding 304L (022Cr19Ni10) and equivalent materials, this rod maintains stable arc performance throughout your production cycle. For applications requiring higher corrosion resistance, consider our molybdenum-enhanced stainless steel rod for chloride-rich environments.

Key Features

• Ultra-Low Carbon Content – C: 0.023% minimizes sensitization and intergranular corrosion risk
• Silicon-Enhanced Formula – Si: 0.75% improves molten pool fluidity and bead appearance
• Balanced Alloy Composition – Cr: 19.80%, Ni: 10.54% delivers reliable corrosion resistance in standard industrial environments
• All-Position Capability – Consistent arc stability for vertical, overhead, and horizontal welding
• Smooth Feeding – Reduced friction and drag for operator comfort during extended sessions
• Minimal Spatter – Silicon addition reduces post-weld cleanup time and material waste
• 5kg Spool Format – Convenient size for job-shop and production environments

Business Advantages for Resellers

• High-Volume Demand: Stainless steel TIG rods remain consistent sellers in food processing, pharmaceutical, and petrochemical sectors
• Premium Margin Potential: Austenitic grades command better markups than mild steel alternatives
• Industry-Specific Applications: Narrow, predictable customer base (QA/medical equipment manufacturers) creates repeat orders
• Stock Efficiency: 1.6mm diameter covers 80% of small-to-medium stainless fabrication work
• Compliance-Friendly: AWS A5.9 / BS EN ISO 14343 certifications reduce customer qualification burden and accelerate sales cycles
