OVERVIEW

Premium Austenitic Stainless Steel MIG Wire

The Bonarc ER308L .030" MIG Wire is a high-performance consumable designed for the welding of austenitic stainless steels. Engineered with a nominal composition of 18% Chromium and 8% Nickel, this wire is specifically formulated to join base metals of similar composition, such as AISI 301, 302, 304, and 304L. The "L" designation indicates an extra-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 a reliable choice for industrial applications involving chemical tanks, food processing equipment, and architectural structures.

Manufactured to strict quality standards, the Bonarc ER308L features precision layer winding on a 5kg spool. This attention to packaging detail ensures consistent wire feeding, reducing the risk of tangles or bird-nesting in the drive rolls. The wire produces a stable arc with excellent wetting characteristics, resulting in flat, smooth weld beads that require minimal post-weld cleaning. It is compatible with standard MIG welding setups utilizing Direct Current Electrode Positive (DCEP) polarity and appropriate shielding gas mixtures, such as Argon/CO2 (98/2) or helium-based tri-mixes.

For industrial fabricators seeking reliability and consistency, this wire meets AWS A5.9 specifications. Its mechanical properties provide strong, ductile joints capable of withstanding the rigors of operational stress. Whether used in general fabrication or specialized maintenance and repair operations, the Bonarc ER308L delivers the metallurgical integrity required for professional results.

FAQ

For the best results, use a mixture of 98% Argon and 2% CO2. A Tri-mix (Helium/Argon/CO2) can also be used for superior bead appearance and wetting.

No, it is recommended to use ER316L wire for welding 316 stainless steel to maintain the molybdenum content required for corrosion resistance in that grade.

This wire runs on Direct Current Electrode Positive (DCEP), also known as Reverse Polarity.

The 'L' stands for 'Low Carbon'. This indicates a maximum carbon content of 0.03%, which prevents carbide precipitation and protects against intergranular corrosion.

It is not recommended. For welding mild steel to stainless steel, you should use ER309L wire to prevent cracking and ensure proper dilution.

This product comes on a standard spool weighing 5kg (approximately 11 lbs).

While the weld itself is corrosion-resistant, MIG welding generally requires shielding gas which can be blown away by wind. It is best used indoors or with windbreaks.

This wire has a diameter of 0.030 inches (0.8mm), making it suitable for light to medium gauge stainless steel.
