36308l045 - ER308L Stainless Steel TIG Welding Rod - 0.045 Inch - 10lb Tube

Premium ER308L Stainless Steel TIG Filler Metal

The Central Wire ER308L TIG Rod (0.045" x 36") is a high-performance stainless steel filler metal designed for the Gas Tungsten Arc Welding (GTAW) process. Engineered to meet the rigorous demands of industrial fabrication, this rod is primarily used for welding austenitic stainless steels such as types 304, 304L, 308, and 308L. The "L" designation indicates a low carbon content (maximum 0.03%), which is critical for preventing carbide precipitation during the welding process. This feature significantly enhances the weld's resistance to intergranular corrosion, making it an ideal choice for applications where the finished product will be exposed to corrosive environments or high temperatures.

This 0.045-inch diameter rod is particularly well-suited for welding thin-gauge materials where heat input control is paramount. The smaller diameter allows for a stable arc and precise puddle manipulation, reducing the risk of burn-through on delicate components. Central Wire ensures a consistent chemical composition and diameter tolerance, providing welders with reliable feeding and predictable arc characteristics. The rods are manufactured with a clean, bright finish, free from surface contaminants that could introduce porosity or inclusions into the weld deposit.

Packaged in a sturdy 10lb tube, these 36-inch cut lengths are protected from environmental moisture and physical damage during storage and transport. Each rod is typically stamped or flagged for easy identification, ensuring compliance with quality management systems in regulated industries. Common applications for this ER308L filler metal include food and beverage processing equipment, chemical storage tanks, pharmaceutical manufacturing systems, and architectural stainless steel structures. It also exhibits excellent toughness at cryogenic temperatures, expanding its utility to specialized industrial sectors.
