TIG Rod ER316L Stainless Steel, 3.2mm Diameter, 1 Meter Length

Brief Overview

This ER316L stainless steel TIG filler rod is engineered for all-position welding of austenitic stainless steels, particularly SUS 316L materials used in petrochemical and chemical equipment manufacturing. The molybdenum content (2.59%) provides superior corrosion resistance to acetic acid, sulfurous acid, phosphoric acid, and salt environments—critical for industries where chemical attack is a constant concern. Stock this alongside compatible ER308LSi stainless rods and aluminum TIG consumables to offer customers a complete TIG welding portfolio.

Key Features

• Molybdenum-Enhanced Composition: 19.12% Chromium, 12.59% Nickel, 2.59% Molybdenum ensures excellent corrosion resistance in aggressive chemical environments
• All-Position Capability: Smooth, spatter-free welds with consistent bead appearance regardless of joint orientation
• Low Carbon Content: 0.023% carbon minimizes sensitization and intergranular corrosion in the heat-affected zone
• Clean Metallurgy: Tight control on phosphorus (0.009%) and sulfur (0.008%) prevents brittleness and improves ductility
• Uniform Diameter: 3.2mm consistent cross-section ensures predictable wire feed and arc stability
• 1 Meter Convenient Length: Compact form factor reduces waste and simplifies storage; 5kg bundle optimizes handling and inventory rotation

Business Advantages for Resellers

• High Margin Consumable: TIG filler rods are regular replenishment items with steady demand in fabrication shops and maintenance operations
• Petrochemical & Chemical Market Leverage: Industries requiring 316L stainless (petrochemical, pharmaceutical, food processing) operate on strict material specifications—no substitutions, reliable repeat orders
• Compact Packaging: 5kg bundles appeal to small-to-medium job shops while supporting larger fabricators' inventory management
• Quality Certification: AWS/ISO/JIS classification simplifies customer compliance documentation and material traceability
• Bundling Opportunity: Pair with complementary stainless rods or mild steel MIG consumables to increase average transaction value

Application Notes

Ideal For:

• Welding of 022Cr17Ni12Mo2 (SUS 316L) plate and pipe
• All-position TIG welding in chemical and petrochemical fabrication
• Equipment exposed to corrosive media requiring superior chemical resistance
• Maintenance and repair welding where material matching is mandatory

Performance Characteristics:

• Excellent weldability across all positions (flat, vertical, overhead)
• Minimal spatter—reduces cleanup time and material loss
• Smooth bead profile—improves appearance and reduces post-weld finishing
• Superior pitting resistance due to molybdenum content—outperforms 304L/308L in acidic and chloride-rich environments
