OVERVIEW

Premium Grade ER308L Stainless Steel TIG Filler Metal

The Bonarc ER308L TIG Rod (1.6mm) is a high-performance filler metal engineered for the precision welding of austenitic stainless steels. Conforming to AWS A5.9 specifications, this rod is specifically formulated with an "Extra Low Carbon" (L-grade) composition, typically containing a maximum of 0.03% carbon. This metallurgical characteristic is critical for industrial applications as it significantly reduces the susceptibility to intergranular corrosion and carbide precipitation, which can occur in the heat-affected zone (HAZ) of standard 308 grades.

Designed primarily for joining base metals of similar composition—such as AISI 304 and 304L—this filler metal contains nominally 18% Chromium and 8% Nickel. This 18/8 composition ensures that the weld deposit matches the mechanical properties and corrosion resistance of the base material. It is also suitable for welding stabilized grades like AISI 321 and 347 in moderate temperature service conditions. The 1.6mm diameter offers excellent control for thin-to-medium gauge materials, making it a versatile choice for pipe welding, sheet metal fabrication, and maintenance operations.

Industrially, Bonarc ER308L is widely utilized in sectors requiring high sanitary standards and chemical resistance, such as food and beverage processing, pharmaceutical manufacturing, and chemical plant maintenance. The rods are supplied in a durable 5kg plastic tube, ensuring the filler metal remains clean and free from contaminants like moisture and dust, which is essential for producing porosity-free, X-ray quality welds.

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 improves corrosion resistance and prevents cracking in the heat-affected zone.

Yes, ER308L is the standard filler metal for welding AISI 304 and 304L stainless steels. It matches the base metal's chemistry and mechanical properties perfectly.

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

Yes, because it is designed for 304/304L stainless steel (the most common food-grade stainless), Bonarc ER308L is widely used in the fabrication of food service and processing equipment.

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

No, for welding mild steel to stainless steel, you should typically use an ER309L filler rod. ER308L is designed for stainless-to-stainless applications.

The exact count varies by length and diameter, but a 5kg tube of 1.6mm stainless TIG rods typically contains approximately 300 to 350 rods, assuming a standard 1000mm length.

A typical ER308L weld deposit has a tensile strength of approximately 85,000 PSI (590 MPa), though this can vary slightly based on welding parameters and base metal dilution.
