TIG Rod ER316L Stainless Steel – Professional-Grade Welding Consumable

Brief Overview

This ER316L TIG welding rod delivers the corrosion resistance and weldability required for high-performance petrochemical and chemical equipment fabrication. The molybdenum-enhanced composition (Mo: 2.59%) provides superior resistance to acetic acid, sulfurous acid, phosphoric acid, and salt environments—essential for industries where material failure directly impacts safety and operational cost. Whether you're stocking inventory for petrochemical fabrication shops or supplying maintenance operations at fertilizer plants, this rod meets AWS A5.9 and international BS EN ISO 14343 standards. Pair it with ER308LSi stainless TIG rods for a complete range of austenitic stainless welding solutions.

Key Features

• All-Position Welding Capability: Delivers consistent, quality welds across flat, horizontal, vertical, and overhead positions
• Low Spatter Output: Reduces post-weld cleanup time and material waste, directly improving labor efficiency
• Smooth, Aesthetically Sound Beads: Reduces secondary finishing and grinding, lowering rework costs
• Molybdenum Alloying (2.59% Mo): Superior pitting resistance in aggressive chemical environments (acetic acid, sulfurous acid, phosphoric acid, salt solutions)
• AWS A5.9 / BS EN ISO 14343 Certified: Meets international welding standards for SUS 316L and 022Cr17Ni12Mo2 base materials
• 1-Meter Rod Length: Efficient material use with minimal stub waste
