EX316L000000450TUN - Exocor ER316L Stainless Steel TIG Welding Rod .045" 10lb

Technical Overview of Exocor ER316L TIG Rod

The Exocor Executive ER316L is a premium quality solid TIG welding rod designed to meet AWS A5.9 specifications for the ER316L classification. This filler metal is engineered for joining Type 316 and 316L austenitic stainless steels. The alloy composition includes approximately 18.5% chromium, 12.5% nickel, and a critical addition of 2.0% to 3.0% molybdenum. This molybdenum content significantly enhances the weld metal's resistance to pitting and crevice corrosion, particularly in chloride-bearing environments, and improves creep strength at elevated temperatures.

A key feature of the "L" designation is the restricted carbon content, limited to a maximum of 0.03%. This low carbon chemistry is vital for preventing sensitization and intergranular carbide precipitation during the welding process, thereby maintaining corrosion resistance in the as-welded condition without the need for post-weld heat treatment. The rod produces a weld deposit with a ferrite number typically between 8 and 12, ensuring excellent resistance to hot cracking while maintaining ductility.

Exocor ensures a high-quality surface finish on these cut lengths, promoting consistent feeding and arc stability. Each rod is typically stamped or embossed for traceability and quality control. This product is suitable for DCEN (Direct Current Electrode Negative) polarity using 100% Argon shielding gas.
