S308011-017 - Hobart ER308L Stainless Steel TIG Welding Rod - 1/16" x 36" (1 lb Tube)

Hobart ER308L Technical Overview

The Hobart ER308L (SKU: S308011-017) is a premium stainless steel TIG welding rod designed to meet AWS A5.9 specifications. This filler metal is formulated for joining austenitic stainless steels, specifically types 304 and 304L. The 'L' designation indicates a low carbon content (maximum 0.03%), which is critical for minimizing carbide precipitation during the welding process. This feature preserves the corrosion resistance of the base metal, particularly in the heat-affected zone (HAZ), making it suitable for applications where post-weld annealing is not possible.

This product is supplied in a 1 lb tube containing 36-inch cut lengths with a diameter of 1/16 inch (1.6mm). The chemical composition typically includes 19.5-22.0% Chromium and 9.0-11.0% Nickel, providing excellent resistance to corrosion and oxidation. Mechanical properties typically exhibit a tensile strength of approximately 87,000 PSI and elongation of 35%, ensuring ductile and durable welds. It is compatible with DCEN (Direct Current Electrode Negative) polarity and 100% Argon shielding gas.

The S308011-017 is manufactured to strict quality control standards, ensuring consistent diameter, cleanliness, and feedability. It is an essential consumable for industrial MRO operations involving food processing equipment, chemical storage tanks, and pharmaceutical infrastructure where sanitary and corrosion-resistant welds are mandatory.
