TIG Rod ER316L Stainless Steel – Premium Corrosion-Resistant Filler Rod

Overview

This ER316L TIG filler rod is engineered for all-position welding of austenitic stainless steel components in demanding industrial environments. The molybdenum content (2.59%) delivers superior corrosion resistance against acetic acid, sulfurous acid, phosphoric acid, and salt exposure—making it ideal for petrochemical and fertilizer equipment fabrication. If your shop also handles aluminium or lower-alloy stainless applications, consider complementary aluminium TIG filler rods or 308LSi stainless alternatives to expand your consumable inventory.

Key Features

• All-Position Capability: Smooth, consistent bead formation without positional limitations
• Low Spatter Profile: Minimizes post-weld cleanup and improves operator efficiency
• Molybdenum-Enhanced Chemistry: C-12Ni-2Mo composition provides excellent resistance to aggressive chemical environments
• Premium Surface Finish: Polished, uniform rod diameter ensures reliable wire feeding and arc stability
• Protective Packaging: Sealed blue sleeve maintains rod integrity and prevents oxidation during storage
• International Certification: Complies with AWS A5.9, BS EN ISO 14343, JIS Z3321, and GB 4241/2 standards

Business Advantages for Resellers

• Recurring Revenue Stream: Consumable product with predictable reorder cycles from fabrication shops
• High-Margin Category: Filler metals command strong profit margins in industrial distribution
• Customer Lock-In: Shops using specific alloy grades (316L for corrosive environments) return consistently
• Cross-Sell Potential: Position alongside complementary stainless TIG rods and welding equipment supplies
• Essential for Specialized Applications: Petrochemical and fertilizer sectors demand certified 316L—non-substitutable in many contracts
