TIG Rod ER308LSi Stainless Steel, 1.0mm Diameter, 1M Length

Brief Overview

This ER308LSi austenitic stainless steel TIG filler rod is engineered for precision welding across all positions. The silicon addition ensures excellent molten pool fluidity, creating clean, aesthetically superior beads with minimal spatter and stable arc characteristics. Whether you're servicing petrochemical equipment, food machinery, or medical device fabrication, this rod delivers the metallurgical consistency your shop demands. Stock this alongside high-molybdenum stainless filler options to cover the full spectrum of industrial stainless applications.

Key Features

• All-Position Capability: Suitable for flat, vertical, overhead, and horizontal welding orientations
• Ultra-Low Carbon Content: 0.023% C prevents sensitization and intergranular corrosion in 304L and similar stainless steels
• Silicon-Enhanced Arc Stability: Si addition promotes smooth feeding, stable arc, and superior bead appearance with reduced spatter
• Austenitic 18Cr-8Ni Matrix: Maintains ductility and corrosion resistance in service temperatures up to 400°C
• Bright Metallic Finish: Clean, polished rods eliminate contamination risk and ensure consistent arc initiation
• Pre-Packaged in Protective Sleeve: Blue plastic tube protects against oxidation and moisture exposure during storage and transport

Business Advantages for Distributors

• High-Volume Industry Demand: Petrochemical, pressure vessel, food processing, and medical equipment sectors consistently specify ER308LSi—this is a staple consumable in any serious fabrication shop
• Repeatable Orders: Once specified by customers for their 304L applications, shops rebuy regularly; position this as a core inventory item
• Margin Opportunity: Stainless filler commands premium pricing; this 1.0mm diameter fills the precision/smaller-job niche where shops cannot compromise on material quality
• Easy Storage & Transport: Compact 5 kg unit with protected packaging reduces damage claims and simplifies logistics
• Standards Compliance: Full AWS A5.9, BS EN ISO 14343, JIS Z3321, and GB 4241/2 certification ensures customer acceptance across export markets

Application Profile

ER308LSi is the industry standard for critical applications where corrosion resistance, low carbon pickup, and aesthetic weld appearance are non-negotiable:

• Petrochemical Equipment: Pressure vessels, piping systems, heat exchangers exposed to aqueous and mild chemical environments
• Food & Beverage Machinery: Stainless food contact surfaces, hygienic equipment requiring FDA-compliant materials
• Medical Device Fabrication: Biocompatible stainless assemblies where weld quality directly impacts device performance
• General Stainless Repair & Fabrication: Any 304L restoration or precision join where traditional mild steel rods are unacceptable

The 1.0mm diameter is ideal for thin-gauge stainless sheet, precision assembly joints, and applications where heat input must be minimized.

Why Distributors Should Stock This Product

Shops that work with austenitic stainless steels cannot substitute this rod without risking customer rejection. Its combination of low carbon, silicon fluidity, and proven standards compliance makes it a non-negotiable item for your inventory. Pair it with alternative high-molybdenum stainless options to offer customers both the workhorse (ER308LSi) and the premium upgrade path (ER316L) for aggressive corrosive environments.
