OVERVIEW

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.

FAQ

The 'L' stands for Low Carbon. ER308L has a maximum carbon content of 0.03%, whereas standard ER308 can have up to 0.08%. The lower carbon content in 308L prevents carbide precipitation during welding, which significantly improves corrosion resistance, especially in the heat-affected zone.

For TIG welding with ER308L, you should use 100% Argon shielding gas. This ensures a stable arc and protects the molten weld pool from atmospheric contamination.

It is not recommended. While it might physically join the metals, ER308L does not contain the Molybdenum found in 316 stainless steel. For welding 316 or 316L, you should use an ER316L filler rod to maintain the corrosion resistance of the base metal.

For TIG welding stainless steel with this rod, use DCEN (Direct Current Electrode Negative), also known as Straight Polarity.

0.045" is relatively thin and is best suited for sheet metal or thin-gauge tubing (approx. 18-14 gauge). For thicker plates (1/8" and up), you would typically want a larger diameter rod like 1/16", 3/32", or 1/8" to deposit metal faster and handle the higher heat input.

No, TIG welding (GTAW) does not use flux. The shielding gas (Argon) provides the necessary protection for the weld pool.

Store them in their original tube in a dry, low-humidity environment. Keeping them clean and free of oil, dust, and moisture is critical for high-quality TIG welds.

Typical mechanical properties for ER308L weld deposits include a tensile strength of approximately 85,000 psi and elongation of roughly 35%, depending on welding parameters and base metal dilution.
